Jiang counted that he'd thrown 90 pitches in a baseball game. He had actually thrown 94 pitches. Calculate the percent error and round to the nearest percent.

The answer is 225 miles per 4.5 hours. hope this ; )

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

90 divided by 5 is 18
