Two glasses of milk and 4 snack bars have a total of 66 carbohydrates (carbs), and 4 glasses of milk and 3 snack bars have a to

musickatia [10]

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.

Help me get this:<br>Y=3x+C<br>

Sedbober [7]

Hi there!

~

$Y = 3x + c$

Simplifying

$Y = 3x + c$

Reorder the terms:

$Y = c + 3x$

Solving

$Y = c + 3x$

Solving for variable 'Y'.

Move all terms containing Y to the left, all other terms to the right.

Simplifying

$Y = c + 3x$

Hope this helped you!

irina1246 [14]

Answer: 60.9 u^2

Step-by-step explanation:

The area of a trapezoid can be calculated as seen in the attachment.

Thus:

$A = \frac{3.7+14.2}{2} * 6.8\\A = \frac{17.9}{2} *6.8\\A = 8.95*6.8\\A = 60.86\\Round\\\left[\begin{array}{c}A=60.9\end{array}\right]$

One batch of walnut muffins uses 1 1/3 cups of walnuts. How many cups of walnuts are needed to make 3 3/4 batches of muffins?

dusya [7]

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 $1 + \frac{1}{3} = \frac{4}{3}$ cups of walnuts.

How many cups of walnuts are needed to make 3 3/4 batches of muffins?

How many cups are required for $3 + \frac{3}{4} = \frac{15}{4}$ batches.

1 batch - (4/3) cups

(15/4) batches - x cups

$x = \frac{4}{3} \times \frac{15}{4} = \frac{60}{12} = 5$

5 cups of walnuts are needed.
