Answer to Problem 7STP

  $55<x<80$

Explanation of Solution

Given information:

The width of the soccer field must be between 55yd and 80yd.

Calculation:

Let the width of the soccer field is ‘ x’yd

Here width ‘ x’ is between 55yd and 80yd.

So, the inequality is

  $55<x<80$

To determine

To List: The possible values for width if the width is multiple of 5.
