A rectangle is x inches wide and 3y inches long. If the length plus twice the width is 12 inches and the length plus the width is 9 inches, what is the length

Answers

Answer 1

Answer:

6

Step-by-step explanation:

12-2(3)=6

9-(3)=6

Answer 2

The length of the rectangle is 6 inches.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

A rectangle is x inches wide and 3y inches long.

If the length plus twice the width is 12 inches and the length plus the width is 9 inches.

That means,

2x + 3y = 12    {equation 1}

x + 3y = 9      {equation 2}.

To solve the system of equations:

Subtract the equation 2 to equation 1.

x = 3

And y = 2.

Therefore, the length is 6 inches.

Answers

Answer: -8r+12

Step-by-step explanation:

Answer:   -8r + 12

============================================

Explanation:

The outer term -2 is multiplied by each term inside

-2 times 4r = -8r-2 times -6 = 12

Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.

I used the distribution property, also known as the distributive property.

That says a*(b-c) = a*b - a*c

In this case, a = -2, b = 4r, and c = 6.

How can Diego package all the 48 brownies and 64 cookies so that each bag has the same combination of items? How many bags can he make, and how many of each will be in each bag? Find all the possible ways to package both items.

I don't know how to do this, can someone please walk me through the process and help with the answer(s)?

Answers

You need to make sure that each bag has the combination of items and they want you to list as many ways as you can think of on how to solve this. One way is:
Divide 48(brownies) by 2, you get 24, and if you divide 64(cookies) by 2, you get 32. So you will need 2 boxes ( since we divided both the numbers by 2 ) and each box will have 24 brownies and 32 cookies in each.
2nd way:
Divide 48( brownies) and 64(cookies) by 4, and you will get 12(brownies) and 16(cookies), so you will need 4 boxes with 12 brownies and 16 cookies in each since we divided the numbers by 4.
So basically, you can keep doing this until no more numbers equal to 48 or 64 when you divide them. And the number you divide them with is how many boxes you will need. Hope this helps.

solve the system of equations using elimination.
X-Y=3
2x+2y=50

Answers

Answer:

abcdefg

Step-by-step explanation:

Answer:

x = 14

y = 11

Step-by-step explanation:

x - y = 3

2x + 2y = 50

multiplty x - y = 3 by two so we can get an equal value

2x - 2y = 6

2x + 2y = 50

-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.

4x = 56

Divide each side by 4 to leave x alone.

x = 14

Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.

14 - y = 3

-y = 3 - 14

-y = -11

y = 11

Now we know that y = 11.

I hope this helps!

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units

Answers

Answer: a) The figure can be reasonably divided into two geometries:

• a rectangular prism

• a hemisphere.

b) The volume of the rectangular prism is given by

  V = lwh

  V = (10 cm)(5 cm)(4 cm) = 200 cm³

The volume of the hemisphere is given by

  V = (2π/3)r³

  V = (2π/3)(3 cm)³ = 18π cm³

c) The total volume of the figure is

  total volume = (prism volume) + (hemisphere volume)

  V = 200 cm³ + 18π cm³

  V ≈ 256.549 cm³

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?

Answers

Answer:

4 wooden and 3 plastic

Step-by-step explanation:

4 (wooden) × 2 - 5 = 3 plastic

3 (plastic) + 4 (wooden) = 7 total

The number of plastic frames is 4 and the number of wooden frames is 3.

What is equation?

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given statement:

The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.

The total number of frames sold by Tristan is 7.

Write the equation for the above statement,

p = 2w - 5

Here, p is a plastic frame and w is a wooden frame,

p + w = 7

Solve the equation by using the elimination method,

p = 4 and w = 3

Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.
