Question

what is F=(9/5)C+32, What is the equivalent Fahrenheit temperature of 5°C?

Answer 1

That's the formula you use if you know a temperature in Celsius and
you want to know what the Fahrenheit equivalent is.

If the Celsius temperature is 5, then the formula says that

                             F = (9/5)(5) + 32 =

                                       (9)      + 32  =  41 degrees Fahrenheit.
