Question

Solve the following equation for f .

Answer 1

f = 3U/2

Step-by-step explanation:
`U\text{ = }(2)/(3)f`

cross multiply:

`\begin{gathered} U\text{ = }(2f)/(3) \\ 3(U)\text{ = 2f} \end{gathered}`

Divide both sides by 2:

`\begin{gathered} \frac{3U\text{ }}{2}\text{= }\frac{\text{2f}}{2} \\ f\text{ = }\frac{3U\text{ }}{2} \end{gathered}`
