Answer:

I think it should be [tex]24x^{2}[/tex]

Step-by-step explanation:

When the question said area of the cube, I think it was supposed to be surface area, which would [tex]6a^{2}[/tex] where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get[tex]6*(2x)^{2}[/tex] which would become [tex]24x^{2}[/tex].

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito. Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.

How much profit would the restaurant make by selling 100 burritos?


What is the cost of making one burrito? (Remember that costs are negative.) Explain how you found your answer.




Write your answer in the space below.

Answers

Answer:

Profit for 100 burritos: $550

Cost to make one burrito: $2.50

Step-by-step explanation:

If a restaurant sells burritos for $8, that's a positive 8 dollars they earned. Then, we need to find what the cost was to make the burrito. If the meat is 1.50 and the cost for all the other ingredients is 1 dollar, then they lose 2.50 for every 8 dollars they make (for each burrito). So, to find the profit in one burrito, we would add -2.5+8, giving us an answer of 5.5. So, they earn 5 dollars and 50 cents each burrito and lose $2.50.

Now, we need to find the profit of 100 burritos

If one burrito is $5.50 in profit, then we take that amount and multiply it by 100. This is to make the illitsratution of selling 100 burritos. So, 5.50*100 would be 550! They would make $550 for 100 burritos, and lose 250 dollars on all of the burrito ingredients.  

the answer is 550 and 2.50

Answers

the division problem is 7 divided by 15. this can be written as 7/15. to do this, you first know that 15 doesn't go into 7, so you add a decimal point, and make the 7 70. 15 goes into 70 4 times. 15 times 4 is 60. 70-60 is 10. 15 doesn't go into 10, so you add another 0 and bring it down. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. 15 doesn't go into 10, so you bring down another 0. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. at this point, you can probably guess that the 6 will go on for a while. this means it is repeating. this means your answer is "a".

A cookie recipe calls for ¾ cup of sugar. You have the
following measuring cups: 1 cup, ½ cup, ⅓ cup, ¼ cup, ⅛ cup, and a tablespoon (which is 1/16 cup).
Suppose your ¼ cup is missing. How would you measure ¾ cups of sugar using at least two of the other measuring cups? Show your work.

Answers

Answer:

1/2 cup and 2 1/8 of a cup

Step-by-step explanation:

1/8 +1/8=1/4

1/2 is equaled to 2/4

so 2/4+1/4=3/4

You need 3/4 cup of sugar and your 1/4 is missing
First use the 1/2 cup which is equal to 2/4
Now a tablespoon is 1/16 of a cup, so use 4 table spoons, which is 1/4 of a cup
You finally have 3/4 cups of sugar because you have 1/2 cups of sugar and 4/6 cup of sugar

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here, option A as 3x+4=7 thus it is an linear equation but an expression is a polynomial where there are no signs such as<,>=

Hence, Option A is the correct answer.
