Question

At 5am the temperature was -13f degrees. At 5pm on the same day the temperature was 39f. Which expression represents the increase in temperature?

A 39- 13
B -13 - 19
C -13 - 39
D 39 - ( -13)

Answer 1

D

Explanation:

Process of elimination, -13 is negative so we eliminate A, There is no 19 in the Math problem so we eliminate B, -13 - 39 would lead to a negative number but since were increasing from temperate it has to be positive so it's not C and answer D would lead to a positive number!
