Question

The linear equation that converts Fahrenheit $\left(F\right)$ to Celsius $\left(C\right)$ is given by the relation
$C=\frac{5F-160}{9}$
If the temperature is ${35}^{0}C$, what is the temperature in Fahrenheit?

• A. $14$
• B. $34$
• C. $86$
• D. $95$

Answer 1

Answer: (D)

$95$

Given, $C=\frac{5F-160}{9}$

Also given, temperature is ${35}^o$.

So, temperature in Fahrenheit is

$35=\frac{5F-160}{9}$

$\Rightarrow 315=5F-160$

$\Rightarrow 5F=315+160$

$\Rightarrow F=95$
