Textbook Problem

In Exercises 18 to 28, first solve each inequality. Then draw a number line graph of the solutions. 5 ( 2 − x ) ≤ 30

To determine

To solve:

The following ineqaulity and draw the number line,

5(2x)30

Explanation

Consider the following inequality,

5(2x)30

Use the distributive property on left side of the equation to get the following,

5(2x)305(2)5(x)30105x30. Since a(bc)=abac

Then substract by 10 on both sides of the inequality to get the following,

105x30105x103010
