Question

please help
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 10 degrees Celsius is.

Answer 1

Solve the equation for F and show all steps. => Make F as the subject

C = 5/9 (F − 32)
1. divide both sides by 5/9
\[\frac{C}{\frac{5}{9}} = \frac{\frac{5}{9} (F − 32)}{\frac{5}{9}}\]\[\frac{9C}{5} = (F − 32)\]
2. add 32 to both sides
\[\frac{9C}{5} = (F − 32)\]\[\frac{9C}{5}+32 = (F − 32)+32\]\[\frac{9C}{5}+32 = F\]
3. Make F on the left
\[F= \frac{9C}{5}+32\]

Answer 2

For part 2, put C =10 into \(F=\frac{9C}{5}+32\)
\(F=\frac{9(10)}{5}+32 = ... ?\)
