Answer:
1) 80+(-20)
2) -13+9
3) -5+(8)
I don't quite know how to explain
Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).
We first find the midpoint of the points:
Midpoint: ((3-3)/2 , (2 + 2)/2)
= (0 , 2)
Thus, the y-axis, where x = 0, is equidistant from the two points.

Step-by-step explanation:
first you subtract 7 from 7 and 12
then you get
(btw the variable always goes first with these problems)
so the final answer would be
