Jamal is putting a swimming pool in his backyard. the length of the pool will be 1/3 of the length of the yard. if the yard is 30 1\2 yards, what will the length of the pool be?

Multiply the two values together
30 1/2 = 61/2
61 x 1
 2     3
61
 6
10 1/6

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
