The answer is C. This is because the red paint must be proportional to the yellow paint, and the proportion given to us is 6/8 (or 6:8 as a ratio). We notice that when simplified, 6/8=3/4, meaning that for every 3 parts of red, there are 4 parts of yellow. By multiplying 3/4 by a certain number of parts for yellow, we'll get the proportionate parts for red.

For example, if you wanted to find out the proportionate part of red for 16 parts of yellow, you would do 3/4*16, which is 12, so that would be 12 parts of red.

21 = − 6 x − 3 x + 4 + 4 x

horsena [70]

Answer:

x=-17/5

Step-by-step explanation:

1. Simplify -6x-3x+4+4x−6x−3x+4+4x to -5x+4−5x+4.

21=−5x+4

2. Subtract 44 from both sides.

21−4=−5x

3. Simplify 21-4 to 17.

17=-5x

4. Divided both sides by -5.

-17/5=x

5. Switch sides.

x=-17/5

Hope this helps.

Pencils cost $7 per carton and erasers cost $4 per carton. If an order comes in for a total of 150 cartons costing $900, what wa

8090 [49]

Let cartons of pencils = P and cartons of erasers = E

Total cartons is 150, so you have P + E = 150

Total cost is $900, so you have 7P + 4E = 900

Rewrite the quantity equation as P = 150 - E

Replace P in the cost equation:

7(150 - E) + 4E = 900

Use the distributive property:

1050 - 7E + 4E = 900

Simplify:

1050 - 3E = 900

Subtract 1050 from both sides:

-3E = -150

Divide both sides by -3:

E = -150 / -3

E = 50

There were 50 cartons of Erasers.

Subtract the number of erasers from the total cartons to get the number of cartons of pencils:

150 - 50 = 100 cartons of pencils.
