Question

Mr. Marsh tells his class that he is thinking of two numbers and wants his students to guess the numbers. He gives them the following hints. The two numbers have a sum of zero. The two numbers have a distance of 2.5 units between them on the number line.

Answer 1

Answer:

1.25 and - 1.25

Step-by-step explanation:

additive inverses: a number and its opposite have a sum of 0

x and y are opposite number, one positive and another negative

distance = 2.5 with midpoint "0"

x = 2.5/2 = 1.25

y = -1.25
