Question

In countries like $USA$ and Canada, temperature is measured in Fahrenheit, Wheres in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius:
$F=\left(\frac{9}{5}\right)C+32$
If the temperature is ${30}^{\circ }C$, what is the temperature in Fahrenheit ?

Answer 1

$F=\left(\frac{9}{5}\right)C+32$

Put $C={30}^{\circ }$

$F=\left(\frac{9}{5}\right){30}^{\circ }+32$

$=9\times 6+32$

$=54+32$

$={86}^{\circ }$F

$\therefore$ the temperature in Fahrenheit is ${86}^{\circ }$F
