<em>subtract 2 from both sides</em>
<em>divide both sides by (-4)</em>
Answer:
x = 8
Step-by-step explanation:
Simplifying
9x + -25 = 5x + 7
Reorder the terms:
-25 + 9x = 5x + 7
Reorder the terms:
-25 + 9x = 7 + 5x
Solving
-25 + 9x = 7 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-25 + 9x + -5x = 7 + 5x + -5x
Combine like terms: 9x + -5x = 4x
-25 + 4x = 7 + 5x + -5x
Combine like terms: 5x + -5x = 0
-25 + 4x = 7 + 0
-25 + 4x = 7
Add '25' to each side of the equation.
-25 + 25 + 4x = 7 + 25
Combine like terms: -25 + 25 = 0
0 + 4x = 7 + 25
4x = 7 + 25
Combine like terms: 7 + 25 = 32
4x = 32
Divide each side by '4'.
x = 8
Simplifying
x = 8
25% is 1/4 so you do 8 times 1/4 and that's 2.
I think that the answer is 16
Answer:
B(x) is the better option
Step-by-step explanation:
Let's say that these functions represent the pay f(x) in hours, x. Function B would increase linearly on a greater scale because each X is being multiplied by 20.
You'll notice this trend for larger numbers, such as 10.
A(x) = 5(10) + 20 = 70
B(x) = 20(10) + 5 = 205
Therefore, your answer is B.
