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. What is a pitcher's Era if he allows 5 earned runs in 18 innings pitched?

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. What is a pitcher's Era if he allows 5 earned runs in 18 innings pitched?

Answer 1

divide both sides of the equation by i

E=9r/i

Answer 2

What is a pitcher's ERA if he allows 5 earned runs in 18 innings pitched?

Answer 3

I gave you the formula. Goodness. can you not put in the numbers, and compute?

Answer 4

To solve the equation Ei = 9r for E, we need to isolate E on one side of the equation.

First, divide both sides of the equation by i to get:

E = 9r / i

Now we can substitute the given values into the equation:
E = 9 * 5 / 18

Calculating this:
E = 45 / 18
E = 2.5

Therefore, the pitcher's ERA (E) is 2.5
