The equation that represents this situation and the definition of the variable x is (a) -4 + x = 15; x = the number of degrees the temperature rose
The given parameters are:
Morning = -4oF
Afternoon = 15oF
Let x represent the change in the temperature.
So, we have
Morning + Change = Afternoon
This gives
-4 + x = 15
Hence, the equation that represents this situation and the definition of the variable x is (a) -4 + x = 15; x = the number of degrees the temperature rose
