## Thinking Mathematically (6th Edition)

Here, we need to convert a temperature in Celsius to its equivalent temperature on the Fahrenheit scale. We will use the following formula, where F = Fahrenheit and C = Celsius. $F=\frac{9}{5}C+32$ C = -5 $F=\frac{9}{5} (-5)+32 = \frac{9}{1}\times (-1)+32 = -9+32 = 23$ For C = -5, F = 23
