Question

The temperature outside is 2° Celsius. The formula for degrees Celsius is: C = 9 over 5 (F − 32), where F stands for degrees Fahrenheit.

Part 1: Solve the formula for F. Show all steps.
Part 2: Determine how many degrees Fahrenheit 2 degrees Celsius is.

Answer 1

Part 1 : C = 9/5(F - 32) --- multiply both sides by 5/9
5/9C = F - 32 -- add 32 to both sides
5/9C + 32 = F

Part 2 : 5/9C + 32 = F
5/9C + 32 = 2
5/9C = 2 - 32
5/9C = -30
C = -30/(5/9)
C = -30 * 9/5
C = - 270/5
C = - 54
