Which of the following best describes the expression 3x + 2y + 8z?The product of three sums; there are three terms
The sum of three products; there are three terms
The product of three sums; there are six terms
The sum of three products; there are six terms

Answers

Answer 1

Answer: The expression above is composed of 3 terms which are: 3x, 2y, and 8z. All of the terms are the product of two items. The first term is a product of 3 and x. The second is a product of 2 and y. Lastly, the third is a product of 8 and z.

Thus, the expression is a sum of three products and there are only three terms. This answer is the second among the four choices.

Answer 2

Answer:

Answer: B The sum of three products; there are three terms

The Moore family is adding a brick patio to their back yard. Mr. Moore is determining howmany square bricks he needs for his rectangular patio, as well as the cost. His sketch is
shown below and is not drawn to scale. Use the formula A=bh to help answer the questions
below.

Answers

I have attached an image showing the sketch and the questions to answer.

Answer:

7) $1.28 per brick paver

8) 64 Sq.inches

9) $0.02 per Sq.inches

10) 0.4444 Sq.ft

11) 120 Sq.ft

12) Number of paver to cover patio = 270

Cost of that number = $345.6

Step-by-step explanation:

7) from the image attached, we can see that a box of 12 pavers cost $15.36.

Thus,cost of each brick paver = 15.36/12

>> $1.28 per brick paver

8) we see on the right of the image attached that the dimension of the brick paver is 8 inches length and 8 inches width.

Thus; square inches is the area = 8 × 8 = 64 Sq.inches

9) 1 paver has an area of 64 Sq. Inches. Thus, 12 pavers has an area of;

12 × 64 = 768 Sq.inches

Since cost of 12 pavers is $15.36

Thus coat per Sq inches of the pavers = 15.36/768 = $0.02 per Sq.inches

10) To find the Sq.ft each paver would cover, we will first convert the dimensions of the paver to ft.

Thus;

Length of 8 inches = 8/12 ft

Width of 8 inches = 8/12 ft

Area = (8/12) × (8/12)

Area = 4/9 Sq.ft = 0.4444 Sq.ft

11) The patio measures;

Length = 12 ft

Width = 10 ft.

Thus;

Area = 12 × 10 = 120 Sq.ft

12) Each paver has an area of 4/9 Sq.ft.

Thus;

Number of pavers to cover the patio = area of patio/area of each paver

Number of pavers to cover patio = 120/(4/9) = 270 pavers

12 pavers cost $15.36

Thus, 270 pavers will cost;

270 × 15.36/12 = $345.6

Answer: 9.40492 units

Step-by-step explanation:

Use the Pythagorean Theorem to solve for the length of each leg of the triangle, then add all lengths to find the perimeter

Line WX has a length of $\sqrt{3^(2)+3^(2) } =√(18) =3√(2)$

Line WY has a length of $\sqrt{3^(2)+1^(2) } =√(10)$

Line XY has a length of $\sqrt{2^(2) } = 2$

The perimeter of the triangle is $3√(2) +√(10) +2=9.40492$

Solve for x: 6x – 8y = 12

Answers

Hi there!

Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.

$6x + 8y = 12$

Step 1) Add 8y to both sides.

$6x - 8y + 8y = 12 + 8y 6x = 8y + 12$

Step 2) Divide both sides by 6.

$(6x)/(6) = (8y + 12)/(6)$

$x = (4)/(3) y + 2$

Final Answer -

$x = (4)/(3) y + 2$

Hope this helps! :D

6x - 8y = 12
6x - 8y + 8y = 8y + 12
6x = 8y + 12

Solve for x. 5(x−2 2/5)=−5.2 Enter your answer as a decimal or simplified mixed number in the box. x =

Answers

Answer:

x = 1.36

Step-by-step explanation:

Final answer:

To solve the equation '5(x-2 2/5)=-5.2', distribute the 5 across the (x-2 2/5) term, add 11 to each side, then divide by 5. This gives us x = 1.16.

Explanation:

The question is asking us to solve the equation 5(x-2 2/5)=-5.2 for x. To do this, we follow several steps:

First, we distribute the 5 across the (x-2 2/5) term. This gives us: 5x - 11 = -5.2
Next, add 11 to both sides of the equation in order to get the x term alone. This results in 5x = -5.2 + 11, which simplifies to 5x = 5.8
Lastly, we divide each side of the equation by 5 to solve for x. This leaves us with x = 5.8/5 = 1.16

Hence the solution to the equation is x = 1.16.
