Chapter 8.1, Problem 64S

To determine

To calculate: To evaluate the expression if $a=12$ and $b=8$

Answer to Problem 64S

Expression is equal to $52$

Explanation of Solution

Given information: Expression is $a+5b$

Calculation:

Expression is given as follows:

  $a+5b$

Here,

  $\begin{array}{l}a=12\\ b=8\end{array}$

Substituting the value in above expression,

  $\begin{array}{l}a+5b=12+5\left(8\right)\\ a+5b=12+40\\ a+5b=52\end{array}$

Hence, on evaluation, expression is equal to $52$
