Question

In baseball, the equation E = 9RI gives a pitcher's earned run average, E where R is the number of earned runs the player is allowed and I is the number of innings pitched. Solve the equation for I.

Answer 1

I =
`(E)/(9R)`

Explanation:

Given

E = 9RI ( isolate I by dividing both sides by 9R )

`(E)/(9R)` = I
