Step-by-step explanation:

0.75 yard = 1 costume

1 yard = 1/0.75 =4/3 costume

6 yards = 4/3 × 6 = 8 costumes

if you wanna check,

8 costumes = 6 yards

1 costume = 6/ 8

= 3/4 (0.75) yard

Answer:

2, only whole numbers are integers

Step-by-step explanation:

An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not.

I hope this helps you :)

Answer:

(3,4)

Step-by-step explanation:

take the mass of Planet X divide by the mass of planet Y. The value u get is the answer

The mass of Planet X is 16.82 times greater than the mass of Planet Y which is determined by division operation.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

We have been given that the mass of Planet X is 8.46 × 10²² kilograms.

And the mass of Planet Y is 5,028,000,000,000,000,000,000 kilograms

We can rewrite the mass of Planet Y as :

⇒ 5.028 × 10²¹

We have to divide the mass of Planet X by the mass of Planet Y

⇒ mass of Planet X / mass of Planet Y

⇒ 8.46 × 10²²/ 5.028 × 10²¹

⇒ 16.82

Therefore, the mass of Planet X is 16.82 times greater than the mass of Planet Y.

Answer:

The paintings itself would be 9 dollars

Step-by-step explanation:

Xavier needs to sell 12 paintings to break even.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say he needs to create x number of paintings for break-even

The total cost of manufacturing;

⇒ 84 + x

Total selling ⇒ 8x

Now for break-even,

Total selling = total cost of manufacturing

8x = 84 + x

7x = 84 ⇒ x = 12

Hence " Xavier needs to sell 12 paintings to break even".

Answer:

x = 5

Step-by-step explanation:

1x + 20/2 = 3x

subtract 1x

1x -1x + 20/2 = 3x -1x =

20/2 = 2x

Identify

20/2 = 20 divided by 2 = 10

10 = 2x

divide by 2

10/2 = 2x/2

5 = x

Option A= 36 + 27 pi is the correct answer

Area of square= 6*6 = 36

Area of the remaining circle = 3/4*pi*r^2

Thus, total area = area of square+ area of circle

36 + 27pi

Answer:

x = 0

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

Call the amount she started with, x

she removes 2

x - 2

then she divides it by 10

(x - 2)/10

each bag contains 7 pieces

(x - 2)/10 = 7

so now solve using inverse operations

(x - 2)/10 = 7

        *10    *10

x - 2 = 70

  +2    +2

x = 72

Answer:

length of each side of the room is 2√30 which is approximately 10.9545 feet

Step-by-step explanation:

The area of the square can be computed as follows:

Area = l²

where l is the length of the side

We are given that:

area = 120 ft²

Substitute with the area in the above equation and solve for l as follows:

area = l²

120 = l²

l = √120

l = 2√30 ft

This is approximately equal to 10.9545 ft

Answer:

[tex]\boxed {x = -2}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]-5x - 4 = 3x + 12[/tex]

-Take [tex]3x[/tex] and subtract it from [tex]-5x[/tex]:

[tex]-5x - 4 - 3x = 3x - 3x + 12[/tex]

[tex]-8x - 4 = 12[/tex]

-Add [tex]4[/tex] to both sides:

[tex]-8x - 4 + 4 = 12 + 4[/tex]

[tex]-8x = 16[/tex]

-Divide both sides by [tex]-8[/tex]:

[tex]\frac{-8x}{-8} = \frac{16}{-8}[/tex]

[tex]\boxed {x = -2}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].

Answer:

x=3.5

Step-by-step explanation:

Answer:

Pretty sure it's x=60

Step-by-step explanation:

0.75x+0.8x+9=101

1.55x+8=101

1.55x=101-8

1.55x=93

and then divide

Answer:

[tex] \sf x = 60[/tex]

Step-by-step explanation:

Given equation,

→ 0.75x + 0.8(x + 10) = 101

Now the value of x will be,

→ 0.75x + 0.8(x + 10) = 101

→ 0.75x + 0.8x + 8 = 101

→ 0.75x + 0.8x = 101 - 8

→ 1.55x = 93

→ x = 93/1.55

→ [ x = 60 ]

Hence, the value of x is 60.
