Chapter 0, Problem 32PG

To determine

To solve the inequality

Answer to Problem 32PG

  $r<\frac{-15}{2}$ is the solution.

Explanation of Solution

Given information:

  $3r+7<r-8$

Calculation:

The given inequality is $3r+7<r-8$

Solving the inequality,

  $3r-r<-8-7$

So,

  $2r<-15$

Dividing by 2,

  $r<\frac{-15}{2}$

Hence, $r<\frac{-15}{2}$ is the solution of the inequality.
