Question

If C is the temperature in degrees celsius and f is the temperature in degrees Fahrenheit, then 9C=5(F-32). If the temperature is 45 degrees celsius what is the corresponding temperature in degrees Fahrenheit

Answer 1

Given:

The relation between f and c is:

$9C=5(F-32)$

The temperature is 45 degrees celsius.

Find-:

The temperature in degrees Fahrenheit

Explanation-:

Temp. in degrees Fahrenheit

$9C=5(F-32)$

Temp. Is:

$C=45\text{ }$$\begin{gathered} 9C=5(F-32) \\ \\ 9\times45=5(F-32) \\ \\ F-32=\frac{9\times45}{5} \\ \\ F-32=9\times9 \\ \\ \end{gathered}$

So, the temp. In degree Fahrenheit is:

$\begin{gathered} F-32=9\times9 \\ \\ F-32=81 \\ \\ F=81+32 \\ \\ F=113 \end{gathered}$

So, the temperature is 113 degrees fahrenheit.
