Step-by-step explanation:

The answer is 12x8x2 so it would be 192

Answer:

24 percent

Step-by-step explanation:

Answer:

the equation will be  2(6x+10+4x+1)

simplified to

12x+20+8x+2

simplified to

20x+22

The perimeter of the rectangle will be 20x+22

Thank you, Hope it helps

Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

7 + m = 4

subtract 7 from both sides

and m= -3

Answer:

180

Step-by-step explanation:

Given :

the number has three digits

it is multiple of 20

hundreds digit and tens digit add to make 9

half of it is less than 100.

I suppose 180 can correctly fit into all above criterions

It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.

Answer: 61.71

Step-by-step explanation:

Answer:

The answer is "x + 4x = 35; 7 large stones and 28 small stones"

Step-by-step explanation:

Please find the complete question in the attached file.

Let

[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]

Users want to use four small stones for each big stone:

[tex]Y = 4x[/tex]

solving the equations system:

[tex]x + y = 35\\\\y = 4x[/tex]

we find:

[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

Answer:

The correct approach is Option A (-4).

Step-by-step explanation:

The given values are:

Vertex of the parabola,

(h, k) = (3, 5)

Passing through,

(x, y) = (-1, 6)

As we know,

The equation of parabola is:

⇒  [tex]x=a(y-k)^2+h[/tex]

On substituting the given values in the above equation, we get

⇒  [tex]-1=a(6-5)^2+3[/tex]

⇒  [tex]-1=a+3[/tex]

On substracting "3" from both sides, we get

⇒  [tex]-1-3=a+3-3[/tex]

⇒           [tex]a=-4[/tex] (coefficient of squared term)

Thus the above is the right choice.

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

Answer:

10m - 15

Step-by-step explanation:

5(2m - 3) = 10m - 15

Step-by-step explanation:

10m-15

(5*2m minus 5*3)

Answer:

35

Step-by-step explanation:

You have 17 either side to make 18 the middle e.g if 2 was the middle then you have 1 either side.

Answer:

36

Step-by-step explanation:

if 18 is the middle there are 17 on each side of that person so 17+17+1=36

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]

[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]

⇒ XZ = [tex]\frac{20*6}{8}[/tex]

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.

Answer:

the equation in numbers looks like this: 6xK-4=2xK+4 and if you are solving this equation it is equal to 0

Step-by-step explanation:

to get to 0 you first need to cancel out the equal terms on both sides so it should look like this: 6K=2K

then you move the variable to the left hand side and change its sign so it should look like this:6K-2K=0

then you collect the like terms so it should look like this: 4K=0

and then you divide both sides by 4 and it should get you K=0

Answer:

40points

Step-by-step explanation:

Given data

Let the total points the team scored be x

so that

20% of x= 8 points

let us solve for x

20/100*x= 8

0.2*x= 8

0.2x= 8

Divide both sides by 0.2

x= 8/0.2

x= 40 points

Hence the time scored 40points

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

Answer:

An example would be

(x+3)-(y+12)

The two constants are 3 and 12 (I'm assuming you meant "constant" as in the number that stands by itself and not "constatant" lol)

The two variables are x and y

The two operations are addition and subtraction

In words you could say "the quantity of x plus three minus the quantity of y plus twelve"
