Question

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F.

F = 9 over 5C + 32

Which of the following formulas correctly solves for C?

C = 5F - 32 over 9

C = 5 F over 9 - 32

C = 9 over 5(F – 32)

C = 5 over 9(F – 32)

Answer 1

F = (9/5)C + 32
subtract 32 from both sides
F -32 = (9/5)C + 32 -32
simplify
F -32 = (9/5)C
times both sides by the reciprical of (9/5)
(5/9)*(F-32)=(9/5)C*(5/9)
simpify
(5/9)*(F-32)=C

Answer 2

So D
