Let $F$ denote a certain temperature in degrees Fahrenheit, and $C$ the same temperature in degrees Celsius. Then you can convert between $F$ and $C$ by the formula $$F = 32 + \frac{9}{5}C.$$
Suppose the temperature is $9$ degrees Celsius.
Enter here the corresponding temperature in degrees Fahrenheit.
Hint: Substitute the value of $C$ in the given formula.
