Chapter 0, Problem 43PFG

To determine

To solve the inequality

Answer to Problem 43PFG

  $b\ge 30$ is the solution.

Explanation of Solution

Given information:

  $-\frac{b}{5}\le -6$

Calculation:

The given inequality is $-\frac{b}{5}\le -6$

Multiplying equation by -5,

  $-\frac{b}{5}\times (-5)\le -6(-5)$

When multiplied by negative number, the inequality flips

  $b\ge 30$

Hence, $b\ge 30$ is the solution of the inequality.
