the temperature outside is - 5 degree F. name the temperature that would make the sum of the two temperatures 0 degree f?

5 °F

Step-by-step explanation:

Let t represent the temperature of interest in degrees F. You want the value of t to satisfly ...

t + (-5) = 0

Add 5 to both sides of the equation:

t - 5 + 5 = 0 + 5

t = 5

The temperature that would make the sum be 0 °F is 5 °F.
