Which expression is equivalent to 4(3x+5y+2z)+3(x-z)
A. 12x+20y+8z
B. 5(3x+4y-z)
C. 15x+20y+5z

Answers

A. 12x+20y+8z...it's a simple distributive property question :)

Final answer:

The expression 4(3x+5y+2z)+3(x-z) is equivalent to 15x+20y+5z.

Explanation:

To simplify the expression 4(3x+5y+2z)+3(x-z), you need to distribute the 4 and 3 to each term inside the parentheses.

When you distribute the 4 and 3, you get 12x+20y+8z+3x-3z. Combine like terms to simplify further, which gives us 15x+20y+5z.

Therefore, the expression 4(3x+5y+2z)+3(x-z) is equivalent to C. 15x+20y+5z.

Divide each cost over the number of bottles

For the 6-pack, we have
3.79 dollars divided by 6 = 3.79/6 = 0.6317 which rounds to 0.63

So we pay $0.63 per bottle or 63 cents per bottle

-------------------------------------

For the 9-pack, we have
4.50 dollars divided by 9 = 4.50/9 = 0.50

meaning we pay $0.50 per bottle or 50 cents per bottle
-------------------------------------

For the 12-pack, we have
6.89 dollars divided by 12 = 6.89/12 = 0.57416 which rounds to 0.57

So we pay $0.57 per bottle or 57 cents per bottle
-------------------------------------

In summary we have
The 6-pack costing 63 cents per bottle
The 9-pack costing 50 cents per bottle
The 12-pack costing 57 cents per bottle

The lowest per bottle cost is 50 cents per bottle, which is for the 9-pack

The 9-pack is the best deal of the three deals. 

If a real estate agent receives 11 percent of the selling price of each house he sells, then what would the agent make if the house sells for $1033,000?

Answers

if you take the percentage out of 1,033,000 you get the answer $113,630

The real estate agent would make $113,630 by earning an 11% commission on the sale of a house priced at $1,033,000.

The real estate agent would receive 11% of the selling price of the house if it sells for $1,033,000. To calculate the commission, we use the formula:

Commission = Selling Price  imes Commission Rate

So, the agent's commission would be:

Commission = $1,033,000  imes 0.11 = $113,630.

Therefore, the real estate agent would make $113,630 from the sale of the house.

In the expression 6pq+8p-6r, what is the coefficient of the term 6pq?

Answers

I believe the answer is 6
A coefficient is the number directly in front of the letters. For example,
the coefficient of 8p is 8. They isolated the coefficient to just one term.

A Term is a small group of whole equation. for example, the terms in this problem would be 6pq, 8p, and -6r.
A constant is a number by itself, so with no number behind it.
A variable is the letter. So in 8p, p is the variable.

All of this is just to give you a deeper understanding for when the problems will require more from you.
If you haven't guessed by now, the final answer is 6.

Evaluate the expression 40÷1+3-(3×7)+7-5

Answers

For this problem, you will have to use PEMDAS  (Parentheses) (Exponents) (Multiplication/Division) (Addition/Subtraction)

First of all, you will want to solve for the values inside the parentheses first

40 ÷ 1+3-(21)+7-5      Now check for anything that includes                                                                   multiplication/division and do that

40+3-21+7-5              All you have left now is addition and subtraction. It                                           must go from left to right, therefore if addition is first,                                       do addition, if subtraction is first, then do subtraction.

Final answer = 24
You need to use PEDMAS for this.


40/1=3-(3 times 7) + 7-5

First the parenthesis. 

(3 times 7 is 21 )

40/1+3-(21)+7-5

Next is exponents but there are none so move on to division.

40/1 = 40

40+3- (21) + 7-5

Then add and subtraction from left to right.

40+3=43

43- 21 + 7-5

43-21 is 22.

22+7-5

7-5 is 2

22+2 is 24

Square X is similar to square Y. The scale factor from square X to square Y is 2.5. The area of square X is 25 cm². What is the area of square Y?

Answers

if scale factor is 2.5 then ratio of the areas = 1:2.5^2  = 1 : 6.25, so:-

Area  of square Y = 25 * 6.25  =  156.25 
Final answer:

The area of square Y is 156.25 cm².

Explanation:

To find the area of square Y, we need to use the scale factor to determine its dimensions. The scale factor is 2.5, which means the side length of square Y is 2.5 times the side length of square X. Since the area of square X is 25 cm², we can calculate the side length of square X by taking the square root of 25, which is 5 cm. Therefore, the side length of square Y is 5 cm * 2.5 = 12.5 cm. The area of square Y is then calculated by squaring its side length: 12.5 cm * 12.5 cm = 156.25 cm².

What is distributive property?

The distributive property simply states that multiplication distributed over addition. Multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

For the given situation,

The expression is 12a + 12b + 12c + 12d.

The formula for the distributive property is expressed as,

a × (b + c) = (a × b) + (a × c).

Answers

10 is the answer.
You  know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.

what is the angle of n

Answers

Answer: 81 degrees

-----------------------------------------------------------------------------------
-----------------------------------------------------------------------------------

Explanation:

The top and bottom lines are parallel as indicated by the same arrow markings on the lines. 

Because they are parallel, this makes the angle x (see attached image) congruent to the 44 degree angle. They are alternate interior angles. So x = 44. 

Using x = 44, we can find the angle y. Use the fact that all three angles of a triangle add to 180 degrees. We'll focus on the top triangle.

x+y+37 = 180
44+y+37 = 180 ... replace x with 44
y+44+37 = 180
y+81 = 180
y+81-81 = 180-81
y = 99

The last step we do is use this y value to find the value of n. Notice how the angle n and angle y combine to form a straight angle (aka straight line). So they add to 180 degrees

n+y = 180
n+99 = 180 ... replace y with 99
n+99-99 = 180-99
n = 81
which is the final answer

-----------------------------------------

Side Note: you can ignore the value of y if you want. Using the remote interior angle theorem, we add up the remote interior angles for the top triangle to get
x+37 = 44+37 = 81
which is the answer we got earlier.

The hotel that the Hutchinson family is staying at on the vacation is shaped like a rectangle prism it is 234 feet long 158 feet wide and 37 feet tall what is the volume of the hotel

Answers

Final answer:

The volume of the hotel that the Hutchinson family is staying at, which is shaped as a rectangular prism, can be found by multiplying its length (234 feet), width (158 feet), and height (37 feet) to get a total volume of 1,371,132 cubic feet.

Explanation:

The hotel that the Hutchinson family is staying at can be considered as a rectangular prism when trying to calculate its volume. The formula for calculating the volume of a rectangular prism is Volume = length × width × height.

The given dimensions of the hotel are 234 feet (length), 158 feet (width), and 37 feet (height). Thus, the volume of the hotel can be calculated by multiplying these dimensions together:

Volume = 234 feet × 158 feet × 37 feet

Calculating, we get:

Volume = 1,371,132 cubic feet.

Therefore, the volume of the hotel is 1,371,132 cubic feet.
