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 25 degrees Celsius is.

Answer 1

\[C = \frac{ 5 }{ 9 } (F - 32)\]

Answer 2

multiply both sides by 9
9C = 5(F-32)
divide both sides by 5
9C/5 = F-32
=>F = 9C/5 +32-----> part a
put C=25
=> F =9(25)/5 +32
=> F =45+32
=> F =77 -----> part b
