To determine

To use a structure to solve an inequality

Answer to Problem 5.2.4P

  $b>3.5$

Explanation of Solution

Given information:

An inequality is given

  $-2.2b<-7.7$

Calculation:

  $-2.2b<-7.7$

Multiply by 10 on both the sides

  $-22b<-77$

Dividing both sides by 22

  $-b<-77÷22$

Multiplying both sides by minus sign

  $b>77÷22$

Solving it further and calculating the final answer

  $b>3.5$
