If r = 12.5 and s = |−13|, which of the following inequalities is not true? r ≠ s r < s r ≥ s r ≤ s

Since the absolute value of any number basically makes the number positive, you can rewrite s = |-13| to s = 13. Now we can simply cross out any inequalities that aren't true
r ≠ s is true because 12.5 ≠ 13
r < s is true because 12.5 < 13
r ≥ s is not true because 12.5 is smaller than 13, not larger
So r ≥ s is the inequality that is not true
