Question

Three inches of snow fell on Monday and 5 inches fell on Wednesday. Which number is the additive inverse of the amount of snow that fell?

Answer 1

Well you had x inches of snow in the beginning so
after monday it was
x+3
after wednesday
x+3+5=x+8
so the invers is the value that you use to get back to x
so if you now have x+8 than the inverse is -8
