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.

Can someone help me with this?

Answer 1

to find F, u can distribute the 5/9 into the parenthesis
for part 2 plug in 20 for the eqn u get for part 1

Answer 2

C = 5/9 (F-32)
Part 1. C=5F/9-(5/9)32
5F/9=C+160/9
F=(9/5)C+(9/5)(160/9)
F=(9/5)C+32

Answer 3

Part 2. As instructed by amk11 substitute 20 for C
F=(9/5)20+32
F=36+32=68 degrees Fahrenheit

Answer 4

For fun find out F when it is -40 degrees Celsius!
