Chapter 0.6, Problem 4E

To determine

To solve the equation $\frac{-a}{8}<5$

Answer to Problem 4E

  $a>-40$

Explanation of Solution

Given Information: $\frac{-a}{8}<5$

Formula Used : Linear inequality with one variable

Calculation:

Given equation is

  $\frac{-a}{8}<5$

To isolate the variable a, multiply by 8 both sides-

  $\frac{-a}{8}\times 8<5\times 8$

This gives

  $-a<40$

To isolate the variable a, multiply by $-1$ both sides and the inequality sign changes-

  $a>-40$

Hence the final answer is,

  $a<-40$
