In countries like USA and Canada, temperature is measured in Fahrenheit, whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius:

$straight F equals open parentheses 9 over 5 close parentheses straight C plus 32$

If the temperature is 30°C, what is the temperature in Fahrenheit?

Solution

straight F equals open parentheses 9 over 5 close parentheses straight C plus 32

When C = 30, then F =

bold F bold equals open parentheses bold 9 over bold 5 close parentheses bold 30 bold plus bold 32

= 54 + 32
= 86

therefore

Required temperature = 86⁰F
