Question

The linear equation that converts Fahrenheit ${(}^{o}F)$ to Celsius ${(}^{o}C)$ is given by the relation: ${}^{c}C=\frac{5F-160}{9}$, then if the temperature is ${86}^o$F, what is the temperature in degree Celsius?

Answer 1

${}^{0}C=\frac{5F-160}{9}$

$F={86}^{0}f$

$9^{0}C=5\times 86-160$

$9^{0}C=270$

${}^{0}C={30}^{0}Celsius$
