Answer:
30°F
Step-by-step explanation:
Let the starting temperature be: x°F
After dropping 5°F, the expression becomes.
The resulting temperature was 25°F
This means:
The variable is x.
The coefficient of the variable is 1.
The constants are -5 and 25
The equation is
We now add 5 to both sides to get:
Therefore the initial temperature is 30°F
