Question

Select the reason that best supports Statement 9 in the given proof.

Answer 1

ANSWER

D. Division property of equality

EXPLANATION

From statement 8 to statement 9, the value of x was found. In statement 8 we have,

$9x=162$

To find x, we have to divide both sides by 9,

$\begin{gathered} \frac{9x}{9}=\frac{162}{9} \\ \\ x=18 \end{gathered}$

This is called the division property of equality because a division was made on both sides to maintain the equality.
