The test scores in your class range from 60 to 100 . Write an absolute-value inequality describing the range of the test scores.
$|x-80| \leq 20$
$|x+20| \geq-20$
$|x-80| \geq 20$
$|x-20| \leq 20$
Final Answer: The absolute-value inequality that describes the range of the test scores from 60 to 100 is \(\boxed{|x - 80| \leq 20}\).
Step 1 :The test scores in your class range from 60 to 100. We are asked to write an absolute-value inequality describing the range of the test scores.
Step 2 :The midpoint of this range is 80, and the distance from the midpoint to either end of the range is 20.
Step 3 :Therefore, the absolute-value inequality that describes this range is |x - 80| ≤ 20. This inequality states that the distance between any test score x and the midpoint 80 is at most 20.
Step 4 :Final Answer: The absolute-value inequality that describes the range of the test scores from 60 to 100 is \(\boxed{|x - 80| \leq 20}\).
