The maximum possible value for 'h' = 6 for the given set of system of inequalities.
What do you mean by system of inequalities?A collection of two or so more inequalities for one or more variables is referred to as a system of inequalities. When a problem necessitates a variety of solutions and those solutions are constrained by more than one constraint, a system of inequalities is used. Inequalities systems are frequently used to describe the constraints on such a solution.For the given set of inequalities;
y ≤ 1/2x - 5
y ≥ 3x - 20
Equation both equation;
(1/2)x - 5 = 3x - 20
x - 10 = 6x - 40
Further simplifying;
-5x = -30
x = 6
Thus, the maximum possible value for 'h' is same as the value find for the x = 6; as h also represents the point on the x-axis.

In the diagram below of triangle LMN, O is the midpoint of LN and P is the midpoint of MN. If OP = 31 - 2x, and LM = 38 + 4x, what is the measure of LM?
Answer: LM= ?
If O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, then the measure of LM = 88
As per the question statement, Triangle LMN where O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, we are supposed to find the measure of LM.
As O is the mid point of LN and P is the midpoint of OP the using the Mid point theorem, we can say that in Triangle LMN
[tex]OP=\frac{LM}{2}[/tex]
Substituting values,
[tex]31-2x=\frac{38+4x}{2} \\2(31-2x)=38+4x\\62-4x=38+4x \\8x = 100\\x=12.5[/tex]
LM = 38 + 4x
[tex]LM = 38 + 4(12.5)\\LM=38 + 50\\LM=88[/tex]
Hence value of LM is 88

Herman is standing on a ladder that is
partly in a hole. He starts out on a rung
that is 6 feet under ground, climbs up
14 feet, then climbs down 11 feet.
What is Herman's final position, relative
to ground level?
Answer:
Step-by-step explanation: His final position relative to ground level should be -3. If he starts out 6 feet under ground that is a negative number. So we have -6. Then he climbs up 14 feet. So we are going to add -6+14 which equals 8. Next it says he climbs down 11 feet. So we have a -11 and we will do 8-11=-3.
So -3 is the answer

If x - 4y = -10 and 2x + 9y= -3 are true equations, what would be the value of 3x+5y?
The value of the expression 3x + 5y will be 47.
How to calculate the equation?It should be noted that an equation is used in Mathematics to show the relationship the exist between different variables.
The given equations are:
x - 4y = -10 ...... i
2x + 9y= -3 ....... ii
Multiply equation i by 2
Multiply equation ii by 1
2x - 8y = -20 ...... iii
2x + 9y = -3. ..... iv
Subtract equation iv from iii
(2x - 2x) (-8y - 9y) = (-20 + 3)
-17y = -17
Then, we have to divide by the coefficient.
y = -17/-17
y = 1
Since x - 4y = -10.
We will then put the value of y = 1 into the equation
x - 4(1) = 10
x = 10 + 4
x = 14
Therefore, 3x + 5y will be:
=3(14) + 5(1)
= 42 + 5
= 47.
In conclusion, the value of 3x + 5y is 47.

you choose, at least one marble is guaranteed to be blue. Is it
possible to figure how many blue marbles are in the jar? If so,
how
many are there?
The number of blue marbles in the jar are 8.
Given, the total number of marbles in the jar = 24.
therefore, total number of all possible outcomes = 24.
Let the number of green marbles in Jar be x.
therefore, the number of favourable outcomes = x.
The probability that the marble drawn is green = x/24
But we have the probability of drawing a green marble = 2/3
x/24 = 2/3
3x = 2 (24)
x = 16
Thus , the number of green marbles in the jar = 16
The number of blue marbles = 24 - 16 = 8

On his first three tests Al averaged 76 out of 100.
What score out of 100 must he get on the fourth
test so his average will be 81?
Al must score 96 in his final test to get an average of 81.
An average or mean is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group.
If every number in a list is the same number, then the average of the numbers in the list is also this number. Every one of the diverse varieties of average shares this characteristic.
The sum of the of the numbers 2, 3, 4, 7, and 9 is 25, the average of the numbers is equal to 25 divided by 5=5.
Let Al scores x on final test.
Average score on first 3 tests=76
Total score on first 3 tests=76×3=228
Total score in 4 tests=228+x
Average score of 4 tests=(228+x)÷4
Average to be obtained in 4 tests=81
therefore we can equate the two expressions to calculate x.
(228+x)÷4=81
or, 228+x=324
or,x=324-228
or, x=96
Hence Al needs to get 96 on his final test so that his average is 81.

Over the last 20 years, technology has improved our access to information and changed the way we communicate. A letter that would have taken days or weeks to arrive can now be sent as an email and reach its recipient almost instantly.
In what ways does algebra act as a tool to improve communication? How does algebra affect how people can learn from each other?
Algebra is a universal language used in communicating ideas, and it therefore improves how people can teach or learn ideas from others
What is algebra?Algebra is the mathematics representation of ideas, problems, situation or solutions using mathematical expressions.
Algebra makes use of numbers, variables, and operators to give value or convey information.
Algebra is therefore an indispensable communication tool that is used in all walks of life to improve understanding of disseminated information, from the original source, to the intended destination and beyond, without, losslessly losing any substance, value or understanding.
With algebra, a doctor speaking a foreign language in a remote location can perform complex and emergency operational procedures based on guidance from another doctor communicating through the internet to his exact location and a local robot that is able translate verbal information into action based on algebraic relationships.
Algebra allows the foreign doctor to obtain or look for specific health metrics and indicators.
It allows the foreign doctor to understand the cost implications as well as to avoid dangerous situations and risk factors which are best specified by algebraic relation, that is understandable to all languages, given that it is based on numbers and variables.
Algebra therefore is one of the main means through which one person can teach another or communicate ideas.

Step-by-step explanation:
A new car is purchased for $26, 000 and over time its value depreciates by one half
every 7 years. How long, to the nearest tenth of a year, would it take for the value of
the car to be $8, 800?
If the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.
Given that the cost of car is $26000 and it depreciates by one half every 7 years.
We are required to find the number of years after which the cost of car will reach $8800.
Because the method of depreciation is not given in question, so we will apply straight line method of depreciation.
Depreciation is the gradual or permanent decrease in the cost of asset due to passage of time and many factors.
Depreciation of 7 years=26000*R*7
13000=26000*R*7
R=13000/26000*7
=7.14%
The cost of car will be $8800,so the depreciation charged will be 26000-8800=$17200
17200=26000*7.14/100 *N
N=1720000/26000*7.14
=9.2652
Because it is slightly larger than 9 so we can approx it as 10 years.
Hence if the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.

On a number line, suppose the coordinate of A is 0, and AR = 17. What are the possible coordinates of the midpoint of AR ?
Step-by-step explanation:
The coordinate of A is 0. It is given that AR = 17. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.
Point R is on Right side of A i.e. at coordinate 17
Point R is on Left side of A i.e. at coordinate -17
In both of these cases AR which is the distance from A to R will be 17.
So, if R is on Right side of A, the midpoint of AR would be:
0+17
÷ = 17/2 = 8.5
2
Or if R is on Left side of A, the midpoint of AR would be:
0-17
÷ = -17/2 = -8.5
2
Thus, the possible coordinates of the midpoint of AR are 8.5 and -8.5

The values of A, B and C are 36, 7 and 3, respectively.
What is the simplified form of the sum of two positive integers?
In this problem we have the addition of two positive integers that are divisible to 2. First, we proceed to decompose each element of the addition as a product of prime numbers:
252 = 2² × 3² × 7
108 = 2² × 3³
The greatest common factor is the greatest integer that can be removed from the addition by distributive property. Then, the greatest common factor is 2² × 3² = 36 and finally:

Given:
Area of the rectangle = 104 sq. inchesLength of the rectangle is 5 inches more than the width.To find: the length and width of the rectangle.
Finding:
Let the width of the rectangle be 'x'
Then the length of the rectangle = x + 5
Now, area of the rectangle = width (length)
=> 104 = x ( x + 5)
=> x² + 5x - 104 = 0
=> x² + 13x - 5x - 104 = 0
=> (x + 13) (x - 5) = 0
Since the lengths can't be negative, x = 5, i.e., the width of the rectangle = 5 inches

When she was practising for the 10K, Mirin timed herself.
Her times ranged from 66 minutes down to 54 minutes.
a) Write her times in tolerance notation as in (.... ± ...) minutes.
b) Now calculate her tolerance using percentages as.... mins (± ...%).
Using the percentage concept, it is found that:
a) Her tolerance is of (60 ± 6 minutes).
b) As a percentage, her tolerance times are of 60 minutes (± 10%).
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
For this problem, the interval is between 54 and 66 minutes, that are both within 6 minutes of the mean of 60 minutes, thus:
a) Her tolerance is of (60 ± 6 minutes).
For item b, we want to find the tolerance as a percentage, that is, the percentage that the tolerance of 6 minutes is from the time of 60 minutes, hence:
P = 6/60 x 100% = 0.1 x 100% = 100%.
Hence:
b) As a percentage, her tolerance times are of 60 minutes (± 10%).
