Enter the value for x that makes the equation 1/2 (4x – 8) + 3x = 36 true.
Answer:
x = 8
Step-by-step explanation:
1/2(4x – 8) + 3x = 36
~Simplify left side
2x - 4 + 3x = 36
~Combine like terms
5x - 4 = 36
~Add 4 to both sides
5x = 40
~Divide 5 to both sides
x = 8

a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?
Answer:
$3000
Step-by-step explanation:
If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.
To find the total tuition, divide 1800 by 0.6:
1800/0.6
= 3000
So, their tuition was $3000

The value of angle APA' is 90°.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a point 'p' which is a fixed point.
Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.
The new triangle formed is triangle A'B'C'.
From the figure, we can clearly see that the angle APA' is a right-angle triangle.
m∠APA' = 90°
Thus, the value of angle APA' is 90°.

What is the value of y in the solution to the system of equations?
One-thirdx + One-fourthy = 1
2x – 3y = –30
Answer:
y-value = 8
Step-by-step explanation:
1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1
which is the same as (4x + 3y)/12 = 1
which is the same as 4x + 3y = 12
add both equations and the 'y' will cancel and you will have 6x = -18
x = -3
2(-3) - 3y = -30
-6 - 3y = -30
-3y = -24
y = 8

1 Evaluate the expression 2a + b - 3 when a=5 and b=2. Please click on "show your work" to set up the problem and show your work. Then, enter your answer in the box to the right. You must complete both of these steps.
Answer:
9
Step-by-step explanation:
From the question,
We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.
We substitute 5 for a and 2 for b in the given expression
2a + b - 3
= 2(5) + 2 - 3
= 10 + 2 - 3
= 12 - 3
= 9

What number is the next term in the number pattern? 1/10, 3/12, 7/14, 13/16, … Enter your answer in the box.
A.21/18
B.19/18
C. 21/16
D.19/18
Answer:
A. 21/18
Step-by-step explanation:
The numerator pattern is adding 2 every time to the difference (ex: difference between 1 and 3 is 2, then difference between 3 and 7 is 4). Meanwhile the denominator is only adding 2 everytime.
A riverbank has been colonized by mink. They are an alien species that attacks local wildlife. The river authority traps and removes the minks. Each year it reduces the number by 60%. What percentage of the mink remain after 4 years?
Answer:
24%
Step-by-step explanation:
it is easy when you multiply 6 and 4 to know how many minks remain
Please answer!!!!!!!
To see if it is possible, you will want to create an equation.
3(4x+2) = 6(2x+2)
As you can see, you will need to use the distributive property for this equation.
12x + 6 = 12x + 12
Remove 6 from both sides.
12x = 12x + 6
Divide 12 by both sides
x = x + 0.5
Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.
Which polynomial can be factored using the binomial theorem?
100x2 + 70x + 49
100x2 + 210x + 49
1,000x3 – 2,100x2 + 1,470x – 343
1,000x3 – 2,800x2 + 1,960x – 343
Answer:C
Step-by-step explanation:
The polynomial can be factored using the binomial theorem is
1,000x³ – 2,100x² + 1,470x – 343.
What is Binomial Theorem?Assertion that the sum of the nth power of the product of two positive integers a and b may be written as the sum of the n + 1 terms of the form for any positive integer n.
If a and b are real numbers and n is a positive integer, then
[tex](a + b)^n =^nC_0 a_n + ^nC_1 a_{n-1} b_1 + ^nC_2 a_{n-2} b_2 + ... 1.[/tex]
Given:
Using Binomial we can write
(a+ b)³ = a³ + b³ + 3a²b + 3ab²
and, (a+ b)² = a² + 2ab + b²
So, 100x²+ 70x + 49 and 100x² + 210x + 49 cannot be factors using Binomial Theorem because the correct expansion would be
(10x+ 7)² = 100x² + 140x + 49
and, 1,000x³ – 2,100x² + 1,470x – 343 can be factored using Binomial theorem.
As, (10x - 7)³ = 1000x³ -2100x² + 1470x - 343.

The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50
