Question

The formula for degrees Celsius is: C = 5 over 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

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

Part 2 :
C = 5(20-32)/9
= -5*12/9
= -60/9
= -20/3
= -6.67 degree Celcius
