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 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.

You would plot 83 on the 83 line and you would plot -113 on the -113 line.
