Chapter 10.4, Problem 17CCR

To determine

To evaluate: The expression for $x=-7$ .

Answer to Problem 17CCR

The value of the expression for $x=-7$ is $5$ .

Explanation of Solution

Given information: The given expression is $\frac{3-x}{2}$ .

Calculation: The given expression is $\frac{3-x}{2}$ .

The given value is $x=-7$ .

Put the value of $x=-7$ in the expression:

  $\begin{array}{l}=\frac{3-x}{2}\\ =\frac{3-(-7)}{2}\\ =\frac{3+7}{2}\\ =\frac{10}{2}\\ =5\end{array}$

Thus, the value of the expression for $x=-7$ is $5$ .
