Question

Which pair of numbers are not opposites? Select one: a. |7| and -7 b. 72 and -72 c. 27 and |-27| d. 27 and -27

Answer 1

Answer is choice C

|-27| = 27 which is positive and not negative
Saying "27 and |-27|" is the same as saying "27 and 27". We can replace |-27| with 27 as they are equal. In order for them to be opposites, one has to be negative and the other positive; however, both are positive.
