The formula $F = \frac{9}{5} C + 32$ can be used to convert temperatures between degrees Fahrenheit ($F$) and degrees Celsius ($C$). What Celsius temperature $C$ has the same value when converted to a Fahrenheit temperature $F$?
F = 9/5 C + 32 SInce we want F = C sub this in
F = 9/5 F + 32
- 4/5 F = 32
F = -5/4 (32) = -5/4*32 = -40
F = 9/5 C + 32 SInce we want F = C sub this in
F = 9/5 F + 32
- 4/5 F = 32
F = -5/4 (32) = -5/4*32 = -40
