Question
A temperature in degrees Celsius, C, is equal to five-ninths times the difference of the temperature in degrees Fahrenheit, F, and 32. Write an equation to relate the temperature in degrees Celsius to the temperature in degrees Fahrenheit. Then determine the Fahrenheit temperature that is equivalent to 25 degrees Celsius.

The relation is
C = (5/9)(F − 32).
To find F when C = 25:
25 = (5/9)(F − 32)
Multiply by 9/5: F − 32 = (9/5)·25 = 45
So F = 45 + 32 = 77°F.
C = (5/9)(F − 32).
