Answer:

Step-by-step explanation:

Suppose the length of the carpet is x ft.

and the breadth of the carpet is y ft.

So the area of the rectangular shape =[tex]length\times breadth[/tex]

Area=[tex]x\times y\ ft.^2[/tex]

Cost of carpet

[tex]=Area\times rate\\=xy\times 2\\=\$\ 2xy[/tex]

Answer:

Use substitution method

-7+(15)=8

8=8

Hope this helps. Have a nice day you amazing bean child.

-7 + 15 = 8

Move the 7 over to the 8, the negative sign becomes a positive.

15 = 7+8

7+8 = 15

15 = 15

Answer:

x = 8

Step-by-step explanation:

Let the number = x

x/6 - 1/3 = x/8

-1/3 = x/8 - x/6

-1/3 = (6x-8x)/48

-1/3 = -2/48x

Divide both sides by -2/48

x = -1/3 ÷ -2/48

= -1/3 × -48/2

= 48/6

= 8

x = 8

The number = 8

Answer:

One solution, x = 8/9

Step-by-step explanation:

One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.

4x + 12 = -y

4x + 12 = -(5(x-4))       <--- substitution here

4x + 12 = -5(x-4)

4x + 12 = -5x + 20     <-- simplifying

4x + 5x = 20 - 12

9x = 8

x = 8/9

Answer:

x=5,y=2

Answer:

✑ [tex] \underline{ \underline{ \sf{First ,\: Let's \: learn \: about \: the \: ratio}}} : [/tex]

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = [tex] \sf{ \frac{30}{40} = \frac{3}{4} = 3:4}[/tex] and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : [tex] \sf{ \frac{a}{b}} [/tex] is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

✎ [tex] \underline{ \underline{ \sf{Now \: let's \: solve : }}}[/tex]

☪ [tex] \underline{ \sf{Solution}} : [/tex]

£ 21 is to be divided between Amy and Ben in the ratio 5 : 2. So, let Amy get £ 5x and Ben get £ 2x.

Then , According to the question , [tex] \text{5x +2x = 21}[/tex]

Solve for x :

⇝ [tex] \sf{7x = 21}[/tex]

⇝ [tex] \sf{ \frac{7x}{7} = \frac{21}{7} }[/tex]

⇝ [tex] \sf{x = 3}[/tex]

The value of x is 3. Now , substitute the value of x in 5x :

Amy received £ 5x = 5 × 3 = £ 15 .

☥ [tex] \boxed{ \boxed{ \tt{Our \: final \: answer \: is \bold{£ \: 15}}}}[/tex]

V=706.85

Step-by-step explanation:

Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.

Formula: V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex][tex]r^{2}[/tex]h ---> V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex]([tex]5^{2}[/tex])(27)

And put the plugged in formula in your calculator and you'll find the answer!

V=706.85

I hope this helped.

Step-by-step explanation:

2/3 × 6/7 = twelve twenty first

Answer: 1/30

5 and 6 both have a common factor of 30

30 will be our ned denominator

1/5 needs to be multipliued by 6

(since 5 times 6 is 30)

and

1/6 needs top be multiplied by 5

(since 6 times 5 is 30)

then you get 6/30 - 5/30 and that is just 1/30

Answer:

I think it might be e=5h someone please correct me if I'm wrong

Step-by-step explanation:

Answer:

e = 5h

Step-by-step explanation:

To find the unit rate (money earned per hour), we divide 10 by 2, which gets us 5. That means $5 is earned per house. If h is the number of houses shoveled, and he earns $5 per house, we can write that as 5h. If e is the money earned, we can write this whole thing as e = 5h.

Step-by-step explanation:

Alright so basically you want to get the same denominator

3/4 = 6/8

And (6/8)/(1/8) = 6

So it's 6.

Answer:

$10.76

Step-by-step explanation:

Just multiply 2.99 by 3.6 and round

Step-by-step explanation:

The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.

Statement A. (vertical angles are congruent)

Statement D. (right angles are congruent)

Triangle AEC is similar to triangle BDC.

Statement E is true but does not help.

Correct statement of proportional side lengths:

BD/AE = CD/CE

x/150 = 200/50

x/150 = 4

x = 600

P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

Answer:

y = 3x + 11

Step-by-step explanation:

Substitute the information into the point-slope form equation.

Point-slope form: y - y₁ = m(x - x₁)

y - 2 = 3(x - (-3))

y - 2 = 3(x + 3)

y - 2 = 3x + 9

y = 3x + 11
