Question

Please help! Using the table of range of values for each weight class, how can you express the Light weight class as an absolute-value? (Hint: Use w for the average weight in each weight class.)

A. |w - 45| ≤ 5
B. |w - 50| ≤ 5
C. |45 - w| ≥ 5
D. |w - 45| ≥ 5

Answer 1

there are 2 equations to solve to find the upper and lower boundaries

w - 45 <= 5 and w - 45 <= -5

w <= 50 w<= 40

the the class is 40 - 50


so A is the answer...

Answer 2
