Question

The formula for the temperature in degree Celsius is C=5/9(F-32) Solve the equation for F.

Answer 1

`F\text{ = }(5)/(9C)\text{ + 32}`

Step-by-step explanation

We have that the formula for temperature in degree Celsius is:

`C\text{ = }\frac{5}{9(F\text{ - 32)}}`

To solve for F, we have to make F subject of formula:

`\begin{gathered} Cross\text{ multiply:} \\ C\cdot\text{ 9(F - 32) = 5} \\ \text{Divide through by 9C:} \\ F\text{ - 32 = }(5)/(9C) \\ \text{Add 32 to both sides:} \\ F\text{ = }(5)/(9C)\text{ + 32} \end{gathered}`

That is the answer.
