Answer:
- milk: 10 carbs
- snack bar: 14 carbs
Step-by-step explanation:
Let m and s represent the carbs in the milk and snack bar, respectively. The given relations are ...
4m +3s = 82
2m +4s = 76
Subtracting the first equation from twice the second gives ...
2(2m +4s) -(4m +3s) = 2(76) -(82)
5s = 70 . . . . . . . simplify
s = 14 . . . . . . . divide by 5
We substitute this into the second equation to find m.
2m +4(14) = 76
m +28 = 38 . . . . divide by 2
m = 10 . . . . . . subtract 28
There are 10 carbs in a glass of milk; 14 carbs in a snack bar.

Hi, to answer this question, first, we have to subtract the amount of fabric used (3yd) to the total fabric that Demarco has (6yd)
6 -3 =3yd
Finally, we have to divide the result by the length of each strip piece (3/4yd)
3÷ 3/4= 4 pieces
There are 4 3/4 yd long strips.
