Question 51056: AT 7 a.m. the temperature was -15 degrees F. By 1 p.m. the temp. increased by 18 degrees F. What was the temp. at 1 p.m.? Answer by junior403(76) (Show Source):
You can put this solution on YOUR website! If the original temp was -15F and it increased by +18F...
We can show that as:
-15+18
or
18-15
which equals 3 degrees F.
Hope this helps.
Good Luck!
