2x + 4y = 10
Substitution

Answers

Answer 1

Answer:

y=1

x=3

Step-by-step explanation:

Multiply 2x by three because if you substitute to y, you would have the multiply.

Write what is left. 6y+4y=10

Combine like terms   10y=10

y=1

x=3

Check      3=3(1)

                     6+4=10

So this solution is correct

See below.

Step-by-step explanation:

The ratio of cats to dogs would be 2/5. This is the simplest ratio, but I assume you are looking for other ratios that are equal to 2/5

Since you did not provide choices to pick from, I can't really answer your question. But, some ratios that are equal to 2/5 are 4/10, 6/15, 8/20, and 10/25.

Answers

Answer:

91

Step-by-step explanation:

the formula for a triangle is base x height divided by 2

The ratio of the perimeter of a square A and square B is 4:3. The side of square B is 3 m less than the side
of square A. What is the length of the side of square A?
please answer

Answers

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12

inches


3. What is the scale factor from the actual flower garden to the new scale drawing?

Be sure to express your ratio in simplest form.

Answers

Answer:

1.) Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.) Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.) Scale factor from the actual flower garden to the new scale drawing = 8:1

Step-by-step explanation:

Given - Penny’s backyard contains a flower garden. The dimensions of the

             actual garden are 5 feet by 7½ feet. A scale drawing of the flower

             garden is 3 inches by 4.5 inches.

To find - 1. What is the scale factor from the actual flower garden to the

                  scale drawing?

              2. If the drawing is enlarged by a scale factor of 5/2, what would    

                  be the dimensions of the flower garden in the new scale

                  drawing?

              3. What is the scale factor from the actual flower garden to the

                   new scale drawing?

Proof -

As we know that,

1 feet = 12 inches

⇒5 feet  = 5×12 = 60 inches

  7½ (= [tex]\frac{15}{2}[/tex]) feet = [tex]\frac{15}{2}[/tex]×12 = 90 inches

∴ we get

The dimensions of the actual garden is 60 inches by 90 inches.

1.)

As,

[tex]\frac{60}{3} = \frac{20}{1} = 20 : 1[/tex]

[tex]\frac{90}{4.5} = \frac{900}{45} =\frac{20}{1} = 20 : 1[/tex]

So,

Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.)

As given,  If the drawing is enlarged by a scale factor of 5/2

⇒Dimensions of flower garden = 3×[tex]\frac{5}{2}[/tex] inches by [tex]4.5 (\frac{5}{2})[/tex] inches

                                                    = 7.5 inches by 11.25 inches

∴ we get

Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.)

Scale factor from the actual flower garden to the new scale drawing = [tex]\frac{60}{7.5}[/tex] = [tex]\frac{600}{75} = \frac{8}{1} = 8 : 1[/tex]

Answers

Answer:

measure of both angles is 52°

Step-by-step explanation:

5x - 28 = 3x + 4

2x - 28 = 4

2x = 32

x = 16

Plug in 16 for 'x': 3(16) + 4 = 48 + 4 = 52°

Answer:

Both are 56°

Step-by-step explanation:

5x-28=3x+4

x=16

A frame is 1 in wide and 4 in tall. If it is enlarged to a height of 20 in, then how wide will it be

Answers

For every four inches it’s one. (4) (4) (4) (4) (4) so 5. The answer would be five wide.

A ratio shows us the number of times a number contains another number. The width of the frame after enlargement is 5 inches.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that the frame is 1 inch wide and 4 inches tall. Now, if the frame is enlarged, then the ratio of the corresponding sides will be equal.

Further, given that height after enlargement is 20 inches. Therefore, if the ratio of the height of the before enlargement and after enlargement is taken, then it will be,

Ratio = After Enlargement/ Before Enlargement

Ratio = 20 inches / 4 inches

Ratio = 5

Now, if we use the ratio to find the width of the frame after enlargement, then the frame width will be,

Ratio = After Enlargement/ Before Enlargement

5 = Width after Enlargement/ Width before Enlargement

5 = Width after Enlargement/ 1 inche

Width after Enlargement = 5 inches

Hence, the width of the frame after enlargement is 5 inches.
