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

Answer:

$E=\frac{9r}{i}$

Step-by-step 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 $i$.

$\frac{Ei}{i}=\frac{9r}{i}$

$E=\frac{9r}{i}$, where $i\neq 0$

Therefore, our required equation would be $E=\frac{9r}{i}$.
