The equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.
What is the equivalent of the given expression?Given the expression in the question;
( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )
First, convert the mixed fractions into an improper fractions.
( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )
( (4×2 + 1/2)x - 3 ) + ( -2 + (1×4 + 3/4)x )
( (8 + 1/2)x - 3 ) + ( -2 + (4 + 3/4)x )
( (9/2)x - 3 ) + ( -2 + (7/4)x )
Now, remove the parenthesis and collect like terms
(9/2)x - 3 + -2 + (7/4)x
(9/2)x + (7/4)x - 3 - 2
9x/2 + 7x/4 - 5
Now, add the two fractions containing x
(9x × 4)+(7x × 2)/8 - 5
( 36x + 14x )/8 - 5
50x/8 - 5
(50/8)x - 5
(25/4)x - 5
Convert 25/4 into an improper fraction
(6 1/4)x - 5
Therefore, the equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.

If m< ABF=7b-24 and m< ABE = 2b, find m< EBF .
Answers
Answer:
∠ EBF = 16°
Step-by-step explanation:
note that EB is the angle bisector of ∠ ABF , then
∠ ABE = ∠ EBF = 2x and
∠ ABF = ∠ ABE + ∠ EBF , that is
7b - 24 = 2b + 2b
7b - 24 = 4b ( subtract 4b from both sides )
3b - 24 = 0 ( add 24 to both sides )
3b = 24 ( divide both sides by 3 )
b = 8
Then
∠ EBF = 2x = 2(8) = 16°

The diver is at a depth of [tex]-5\frac{1}{15}[/tex].
_____________________________________
What we have given:
Initial dive: [tex]1\frac{2}{3}[/tex] = [tex]x[/tex]
Additional dive: [tex]3\frac{2}{5}\\[/tex] = [tex]z[/tex]
Given the context, we can assume that sea level is 0ft.
So we have:
[tex]d=0-1\frac{2}{3}-3\frac{2}{5}[/tex] (d = depth)|
[tex]d=0-\frac{5}{3}-\frac{17}{5}[/tex] <- Convert mixed numbers to improper fractions.
[tex]d=-\frac{5}{3}-\frac{17}{5}[/tex] <- Simplify.
[tex]d=-\frac{25}{15}-\frac{51}{15}[/tex] <- The LCM between 3 and 5 is 15, so adjust the fractions accordingly.
(NOTE: Remember everything you do to the denominator must be replicated on the numerator as well!)
[tex]d=\frac{-25-51}{15}[/tex] <- Since the denominators are equal, combine the fractions.
[tex]d=\frac{-76}{15}[/tex]
[tex]d=-\frac{76}{15}[/tex] <- Apply the following fraction rule = [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]d=-5\frac{1}{15}[/tex] <- Convert the improper fraction to a mixed number and there is your final answer.

Bob is interested in examining the relationship between the number of bedrooms in a home and its selling price. After downloading a valid data set from the internet, he calculates the correlation. The correlation value he calculates is only 0. 5. What does bob conclude?.
Answers
According to the calculations made by Bob after downloading and calculating the correlation value as 0.5 from a given data set, he concludes that as the number of bedrooms in a particular home increase there is an increase in the selling price of the bed.
This increase in the selling price due to the increase in the number of bedrooms can be explained with the help of the Law of Demand which states that as the demand for a certain product increases its cost or the selling price also increases.
Thus, when Bob calculates the correlation factor, he finds that as the number of bedrooms increases there is also a hike in the selling price. As there should be a surplus to fulfill the demand for bedrooms.

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13). The measures of the angles RIG and ZIM are 59° and 140°, respectively.
What are the variables behind a geometric system formed by three lines?
In this problem we find a geometric system generated by lines GZ, AM and IR, in which two variables are shown (x, z) and whose values can be found by applying the concepts of complementary and supplementary angles.
A group of angles are complementary if the sum of their measures equals 90°, and supplementary if that sum equals 180°. This system can be represented by the following system of linear equations:
(3 · x - 56) + 90 + (4 · z + 7) = 180 (1)
(4 · z + 7) + (x + 2) = 90 (2)
By (1):
(3 · x - 56) + (4 · z + 7) = 90
3 · x + 4 · z - 49 = 90
3 · x + 4 · z = 139 (1b)
By (2):
x + 4 · z = 81 (2b)
The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13).
Then, the measures of the angles RIG and ZIM are, respectively:
m ∠ RIG = 4 · z + 7
m ∠ RIG = 4 · 13 + 7
m ∠ RIG = 59°
m ∠ ZIM = 360° - (3 · x - 56) - 90° - (4 · z + 7) + (x + 2)
m ∠ ZIM = 360 - 3 · 29 - 56 - 90 - 4 · 13 + 7 + 29 + 2
m ∠ ZIM = 140°
The measures of the angles RIG and ZIM are 59° and 140°, respectively.

180g = 0.180 kg or there are 0.180 kilograms in 180 grams.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
The sentence states an equality between a units of weight in grams (g) and kilograms (kg).
From there, we can say that we are asked how many kilograms are there in 180 grams.
Converting grams to kilograms, we must use the conversion

HELP!! PLEASE!! DUE!! TODAY!! Joanna's vegetable Garden covers an area of 1/6 of a square mile. if the garden is 1/4 mile wide, how long does the garden stretch?
Answers
The garden will stretch by 2/3 miles.
Given that Garden covers an area of 1/6 of a square mile and the garde is 1/4 mile wide.
As we know, the garden is a rectangle shape.
Here, we will use the formula of area of rectangle.
Area of rectangle is equal to the product of length and breadth.
Area =l×b
Here, the give area=1/6 miles² and b=1/4 mile.
Now, we will substitute the values in the formula, we get
1/6=l×(1/4)
Further, we will multiply both sides with 4, we get
4/6=4l/4
4/6=l
Now, we will simplify the left hand side, we get
2/3=l
Hence, the length of garden stretch when garden covers an area of 1/6 of a square mile and 1/4 mile wide is 2/3 mile.

Center (6, –3); r = 8
Center (7, –5); r = 8
Center (6, –3); r = 64
Center (7, –5); r = 64
Answers
According to the question, the standard equation for the circle is [tex]x^{2} +y^{2} =r^{2}[/tex] in which the points (x, y) are the circumference point and 'r' is the radius of the circle.
The given expression for the circle is shown below:
[tex]x^{2} +y^{2} -12x+6y-19=0[/tex]
Bring same variable terms to one side and again re-write the expression:
[tex]x^{2} -12x+y^{2} +6y-19=0[/tex]
Now, to do factors of the given expression add and subtract 36,9 on both the sides
[tex]x^{2} -12x+36+y^{2} +6y+9=19+36+9[/tex]
Factors can be re-written as:
[tex](x-6)^{2} +(y+3)^{2}=64[/tex]
Comparing the calculated equation for the circle with the standard equation, we circle
The center points as (6,-3) and radius as (r = 8).
Hence, the correct answer is Center(6,-3), r = 8.

Answers
The measure of the angle 2 is 122°.
What is referred as the linear pair?When lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to one another after the two lines intersect, they are said to be linear. The sum of the angles of the a linear pair will always be 180°. These angles are also referred to as supplementary angles.Given that angles 1 and 2 form a linear pair,
angle 1 + angle 2 = 180 degrees —— (1)
We've also been notified that angle 2 is 6 times the size of angle 1.
That is to say: angle 2 = (2×angle 1) + 6 ———- (2)
Putting the angle 2 value in (1) from (2)
180 = angle 1 + 2×angle 1 + 6
3×angle 1 = 174
1st angle = 58 degrees ———-(3)
(1) and (3) come from:
angle 2 + 58 = 180
2nd angle = 122 degrees
As a result, angle 2 has a measure of 122 degrees.

7 grade go math lesson 1.1 adding integers with a common sign
Answers
Adding integers with a common sign.
When adding two integers with a common sign, we just add the absolute value of the numbers and the resulting answer is marked with the same sign given in the question.
This question has two possible answers.
Possibility 1:
Both the integers are of positive sign. As a result, the resulting integer after addition is positive.
Example:
Let c = 45 and d = 53.
The sum of c and d is then
sum = c + d = 45 + 53 = 98
Possibility 2:
Both the integers are of negative sign. As a result, the resulting integer after addition is negative.
Example:
Assume c = -23 and d = -61.
The sum of c and d is then
sum = c + d = (-23) + (-61) = -(23 + 61) = -84

A 0
B 3/4
C 2
D no solution
E infinitely many solutions
I will give 80 points
Answers
Answer: E: Infinitely many solutions
Step-by-step explanation:
Starting with 5x - 7x + 6, let's combine like terms.
5x - 7x is -2x.
Thus, we have -2x + 6 = -2(x-3)
Using the distributive property for the right side, we multiply -2 * x, and get -2x, and -2 * -3 and get +6.
Now we have -2x + 6 = -2x + 6. We have the same equation here, and know that there is infinitely many solutions here off the bat.
For sake of computations, let's solve and show our work.
Subtracting 6 from both sides, we have -2x = -2x.
Adding 2x to both sides, we get 0 = 0.
Thus, we have infinitely many solutions.
