Chapter 6.7, Problem 24E

To determine

To evaluate : the expression $5yz$ when $y=-3$ and $z=4$ .

Answer to Problem 24E

The value of the expression is $-60$ .

Explanation of Solution

Given information :

The expression is $5yz$ .

Calculation :

To evaluate the expression, it is needed to substitute $-3$ for $y$ and $4$ for $z$ in expression $5yz$

Therefore, the value of the expression is obtained as:

  $\begin{array}{l}5yz=5\left(-3\right)\left(4\right)\\ 5yz=-15\left(4\right)\\ 5yz=-60\end{array}$

Hence,

The value of the expression is $-60$ .
