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