Answer: Calculate areas for 2 rectangles;

21*9= 189

18*42= 756

make an equation with data you have;

If 189 cost $1.31

756 cost $x

____________

756 *1.31 / 189 = $5.24 cost for second fabric

Second way;

(18x42) / (21x9) = 4 x 1.31 = $5.24

Answer:

x=20

Step-by-step explanation:

So we have [tex]\frac{x}{24} =\frac{30}{36}[/tex]

divide 30/36 to get

[tex]\frac{x}{24} =.833[/tex]

then multiply that by 24

[tex]x=.833*24[/tex]

which will get you

[tex]x=20[/tex]

The value of x from the given proportion is 20.

The given proportion is x/24 = 30/36.

Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Here, x/24 = 5/6

x/4 = 5/1

x=20

Therefore, the value of x from the given proportion is 20.

Answer:

24 is the answer.

Step-by-step explanation:

4 + 4 + 4 + 4 + 4 + 4 = 4 x 6

8 + 8 + 8 = 24

24 = 24

Therefore, 6 = 24 ÷ 4

Answer:

Step 1: Simplify both sides of the equation.

2w=1/4

Step 2: Divide both sides by 2.

2w/2=1/4/2  

Answer:

w=1/8

Answer:

So what you have to do is that first, you simplify both sides of the equation.

(2w = 1/4). Then you divide both sides by 2, (2w / 2 = 1/4 / 2). So after you do that, your left with w = 1/8. So W is equal to 1/8.

Answer:

297 is the surface area

Step-by-step explanation:

Ok this problem is very simple.

First lets define some equations.

Area of a triangle: A = 1/2BH

A = Area   B = Base   H = Height

This equation works for right triangles only.

(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).

Area of a square: A = BH

Surface area equals all the areas of each side added together.

First lets find the area of one of the triangles.

We know 11 is the base and 8 is the height but the triangle isn't a right triangle.

To make it a right triangle divide the base by 2 so 11/2.

You will get 5.5.

Now find the area!

A = 1/2BH

A = 1/2(5.5)(8)

A = 1/2(44)

A = 22

So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).

22(2)=A

44=A

44 is the area of one side of the pyramid but there are 3 other sides (not including the base).

So just do:

44+44+44+44 = A

176 = A

Surface area for the triangles is 176!

Now we must find the area of the square.

A = BH

A = 11(11)

A = 121

Total surface area is all the areas added together so it's:

121+176=A

297

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)
