Question

which of the following is the solution to the equation 25(z-2 )= 125?

A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5

Answer 1

Answer:

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

$z - 2 = \frac{125}{25}$

2) Simplify 125/25 to 5.

$z - 2 = 5$

3) Add 2 to both sides.

$z = 5 + 2$

4) Simplify 5 + 2 to 7.

$z = 7$

Thus, the answer is z = 7.
