Answer:

- 5 < x < 31

Step-by-step explanation:

Inequalities of the type | x | < a, always have a solution of the form

- a < x < a

given | x - 13 | < 18, then

- 18 < x - 13 < 18 ( add 13 to all 3 intervals )

-5 < x < 31

Rewrite the inequality without the absolute value

-18 < x - 13 < 18

Add 13 to the whole equation

-18 + 13 < x < 18 + 13

Simplify

-5 < x < 31

Answer:

73.68%

Step-by-step explanation:

To find the amount of increase subtract 33-19 to get 14.

The percent increase is the amount of increase/initial length * 100

So 14/19*100 = 73.684...

Rounding to the nearest hundredth = 73.68%

You'll get: s ≥ 22 <That would be your answer
