# How do you evaluate (5wx)/z if w=6, x=0.4, y=1/2, z=-3?

See a solution process below:

#### Explanation:

To evaluate this expression substitute:

$\textcolor{red}{6}$ for $\textcolor{red}{w}$

$\textcolor{b l u e}{0.4}$ for $\textcolor{b l u e}{x}$

$\textcolor{g r e e n}{- 3}$ for $\textcolor{g r e e n}{z}$

$y$ is extraneous and not needed for this problem.

Substituting and calculating gives:

$\frac{5 \textcolor{red}{w} \textcolor{b l u e}{x}}{\textcolor{g r e e n}{z}}$ becomes:

$\frac{5 \times \textcolor{red}{6} \times \textcolor{b l u e}{0.4}}{\textcolor{g r e e n}{- 3}} \implies \frac{30 \times \textcolor{b l u e}{0.4}}{\textcolor{g r e e n}{- 3}} \implies \frac{12}{\textcolor{g r e e n}{- 3}} \implies - 4$
