2m + 4s = 66.
4m + 3s = 84.
(Double the 2 glass of milk and 4 snack bars)
4m + 8s = 132.
4m + 3s = 84.
(Take away the second equation from the first equation)
5s= 48.
s = 48/5.
s = 9.6.
4m + 3(9.6) = 84.
4m + 28.8 = 84.
4m = 84 - 28.8.
4m = 55.2.
4m/4 = 55.2/4.
m = 13.8.
In a glass of milk, there are 13.8 carbs, and in a snack bar, there are 9.6 carbs.
2(13.8) + 4(9.6) = 66.

Answer: 60.9 u^2
Step-by-step explanation:
The area of a trapezoid can be calculated as seen in the attachment.
Thus:
![A = \frac{3.7+14.2}{2} * 6.8\\A = \frac{17.9}{2} *6.8\\A = 8.95*6.8\\A = 60.86\\Round\\\left[\begin{array}{c}A=60.9\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B3.7%2B14.2%7D%7B2%7D%20%2A%206.8%5C%5CA%20%3D%20%5Cfrac%7B17.9%7D%7B2%7D%20%2A6.8%5C%5CA%20%3D%208.95%2A6.8%5C%5CA%20%3D%2060.86%5C%5CRound%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7DA%3D60.9%5Cend%7Barray%7D%5Cright%5D)

Answer:
5 cups of walnuts are needed.
Step-by-step explanation:
This question can be solved using a rule of three.
One batch of walnut muffins uses 1 1/3 cups of walnuts.
So one batch of walnut muffins uses
cups of walnuts.
How many cups of walnuts are needed to make 3 3/4 batches of muffins?
How many cups are required for
batches.
1 batch - (4/3) cups
(15/4) batches - x cups

5 cups of walnuts are needed.
