Peggy is cutting a 20 foot roll of ribbon into 2 inch strips for her mother. if peggy has already cut 42 pieces, how many more pieces are left to cut?

Let's do this problem step-by-step. There are 12 inches in a foot, right? So first, multiply 12 and 20, which is 240. So they have 240 inches of ribbon. Now they need to cut the pieces into two-inch pieces, so I would divide by 2 next. 240 divided by 2 is 120. Then, all you have to do is subtract 42 from 120, which is 78. There are 78 pieces left to cut. Hope this helps!

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
