Question

The formula for degrees Celsius is: C = 5/9(F - 32), where F stands for degrees Fahrenheit.

Part 1: Solve the equation for F and show all steps.
Part 2: Determine how many degrees Fahrenheit 20 degrees Celsius is.

Answer 1

1) C = (5/9)(F-32)
F - 32 = (9/5)C
F = (9/5)(C) + 32
2) Plug and solve:
The answer is 68. Try for yourself.

Answer 2

9/5 = 1.8

F = 9/5 * 20 + 32

or

F = 1.8 * 20 + 32
