-x+2y

You have 3x+y and you need to make it 2x+3y

The difference between 3x and 2x is 1x(x)

And the difference between y and 3y is 2y

For the x you have to minus x from 3x to get 2x,(3x-x=2x)

For the y you have to add 2y to y to get 3y,(y+2y=3y)

Now add them
=3x+y+-x+2y=2x+3y

Therefore you add -x+2y

Answer:

<h2><u><em>-x+2y</em></u></h2>

Step-by-step explanation:

What must be <u><em>added</em></u> to 3x + y to get 2x + 3y?

3x + y + z = 2x + 3y

3x + z = 2x + 3y - y

3x + z = 2x + 2y

z = 2x-3x+2y

z = <u><em>-x+2y</em></u>

<u><em>-------------------</em></u>

check

3x + y + (-x) +2y =

<u><em>2x + 3y</em></u>

<u><em></em></u>

<u><em>the answer is good</em></u>

A vendor prepares 100.00 hotdogs every day and sells at $20.00/piece. For each hot dog, he spends $12.00 in the raw material. Ad
astra-53 [7]

Answer:

$397.34 (if he sold the 20 leftover hot dogs), $297.34 if he didn't.

Step-by-step explanation:

We are going to assume that a month has 30 days.

  • First, we are going to see how much money the vendor got from selling the 80 hot dogs. He sold 80 hot dogs at 20 dollars/piece = 1600 dollars.

  • We need to subtract the amount of money he spent in each hot dog (12 dollars in raw material plus one dollar for packing): 13 dollars x 100 hot dogs he prepared = 1300 dollars

  • He also spends a total of 80 dollars per month in truck rent, electricity and other expenses. If we divide this by the amount of days per month we have: 80/30 = 2.66

  • The problem doesn't tell us that there were unhappy customers that day so that amount is zero.

  • We are going to assume that the vendor sold the remaining 20 hot dogs at 5 dollars/piece. 20 x 5 = 100.

Thus, the profit for that day is:

1600 - 1300 - 2.66 + 100 = 397.34

<u>(</u><u>Note:</u><u> If the vendor did not sell the leftover hot dogs and he actually only sold 80 hot dogs, then the profit would be: 1600 - 1300 - 2.66 = 297.34)</u>

Given: 3x + y = 1.<br>  Solve for y. <br> A. y = -3x + 1<br> B.y = -3x - 1<br> C.y = 3x - 1
RUDIKE [14]
Y=-3x+1
So the answer is A. All you're doing is moving the 3x to the opposite side, and because your switching the side, you need to switch the sign. So it's a negative 3x after you solve for y. Solving for y(or any letter) is just getting that letter alone on one side of the equal sign.

A recipe for bread uses 5 3/4 cups of white flour and 3 1/3 cups of wheat flour. How many more cups of white flour than wheat fl
natita [175]
The equation is just 5 3/4 times 3 1/3. You make the denominators the same by multiplying them by each other. It will be 5 3/12 times 3 1/12. Now you times these two together. You can do this part yourself because it will be confusing on here. I hope i helped atleast a little.

11. You are asked to put a V-shaped roof on a house. The slope of the roof is 53°. What is the measure of the angle needed at th
Anestetic [448]
The question said that it told you the base angles. A roof would have two equal base angles. The base angles= 53

All the angles of a triangle each 180, (the roof is shaped like a triangle)

So, let's make x the missing angle.

53(2)+x=180

106+x=180

Subtract 106 on both sides.

180-106= 74

The vertex angle is 74.

I hope this helps!
