Question

To find a baseball pitcher's earned run average (ERA), you can use the formula Ei=9r, where E represents ERA, i represents number of innings pitched, and r represents number of earned runs allowed. Solve the equation for E ...?

Answer 1

You have the formula
E i = 9 r
You can divide both sides by i and get
E = (9 r) / i
The formula is solved for e.

Answer 2

`E=(9r)/(i)`

Explanation:

We have been given an equation
`Ei=9r`, where
`E` represents ERA,
`i` represents number of innings pitched, and
`r` represents number of earned runs allowed.

To solve the given equation for
`E`, we need to separate
`E` on one side on equation.

To separate
`E` on one side on equation, we will divide both sides of equation by
`i`.

`(Ei)/(i)=(9r)/(i)`

`E=(9r)/(i)`, where
`i\\eq 0`

Therefore, our required equation would be
`E=(9r)/(i)`.
