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?
divide both sides of the equation by i
