Answer:

x=60

Step-by-step explanation:

I'm assuming you meant this: (x/5)-8=4

In which case you would add 8 to both sides to get rid of the 8 on the left (your goal is to get x by itself so you want to move the numbers on the x side to the other side of the equal sign)

(x/5)=12

Then you would multiply 5 on both sides to get rid of the fraction with the 5 on the bottom on the left side.

x=60

There's your answer.

Answer:

Part A) [tex]h=V/(\pi r^{2})[/tex]

Part B) [tex]h=4\ cm[/tex]

Step-by-step explanation:

Part A)

we have the formula of the volume of a cylinder

[tex]V=\pi r^{2}h[/tex]

Solve for h

That means ----> isolate the variable h

Divide both side by πr²

[tex]V/(\pi r^{2})=\pi r^{2}h/(\pi r^{2})[/tex]

Simplify

[tex]V/(\pi r^{2})=h[/tex]

Rewrite

[tex]h=V/(\pi r^{2})[/tex]

Part B) Find the height of a cylinder with a volume of 36π cm3 and a base with a radius of 3 cm

we have

[tex]V=36\pi\ cm^3[/tex]

[tex]r=3\ cm[/tex]

substitute in the formula and solve for h

[tex]h=36\pi/(\pi 3^{2})[/tex]

[tex]h=4\ cm[/tex]

To solve for h in the formula V = πr2h, divide both sides of the equation by πr2 to isolate h. The height of a cylinder with a volume of 36π cm3 and a base radius of 3 cm is 4 cm.

To solve the formula V = πr2h for h, we need to isolate h on one side of the equation. To do this, divide both sides of the equation by πr2. This gives us the equation h = V/(πr2). Therefore, the correct formula for solving for h is h = V/(πr2).

To find the height of a cylinder with a volume of 36π cm3 and a base radius of 3 cm, substitute the given values into the formula h = V/(πr2). This gives us h = 36π / (π * 32). Simplifying further, h = 36 / 9 = 4 cm.

For the pencils, she paid: 6 × $0.24 = $1.44

For the pens, she paid: 5 × $0.79 = $3.95

Answer:

x = -11

Step-by-step explanation:

First subtract 5x from both sides (6x - 5x) and the equation turns into: x + 3 = -8. Then subtract 3 from both sides, -8 - 3, and that equals -11. And so the final answer is -11.

The value of x from the equation 6x + 3 = 5x − 8 is -11.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given equation ; 6x + 3 = 5x − 8

Solve for x:

6x + 3 = 5x − 8

First subtract 5x from both sides

6x + 3 - 5x = − 8

x + 3 = -8

Then subtract 3 from both sides;

x = -8 - 3

x = -11

Thus, the final answer is -11.

Therefore, The value of x from the equation 6x + 3 = 5x − 8 is -11.

Answer:  The required length of DE is 29.

Step-by-step explanation:  We are given that DF = 42 in the figure shown.

We are to find the length of DE.

From the figure, we note that

[tex]DE=7x+1,~~EF=4x-3.[/tex]

According to the given information, we have

[tex]DF=42\\\\\Rightarrow DE+EF=42\\\\\Rightarrow 7x+1+4x-3=42\\\\\Rightarrow 11x=42+2\\\\\Rightarrow 11x=44\\\\\Rightarrow x=\dfrac{44}{11}\\\\\Rightarrow x=4.[/tex]

Therefore, we get

[tex]DE=7x+1=7\times4+1=28+1=29.[/tex]

Thus, the required length of DE is 29.

The length of DE using the measurements DF = 42, DE = 7x + 1 and EF = 4x - 3 is 29 unit.

given that,

the length of DF = 42

length of DE = 7x + 1

and, length of EF = 4x - 3

Now, from the figure

DE + EF = DF

Plugging the values back to the formula as

7x + 1 + 4x - 3= 42

Combine like terms

11x - 2 = 42

add 2 both side

11x = 42 + 2

11x = 44

Divide both side by 11

x= 44/11

x= 4

So, the length of DE is

= 7x + 1

= 28 + 1

= 29

Answer:

32 tanks

Step-by-step explanation:

since 562/18

is 31.222222...

You would have to round up because you the limit is 18 fish. You would need 32 tanks to fit all the fish

Answer:

32

Step-by-step explanation:

You have 562 gold fish and you need to have 18 in each tank, how many tanks do you need?

You first need to start with dividing the gold fish amount to the amount that can fit in each tank, (562 divided by 18 = 31.22222222222222). Then you multiply 18 by 31 and you get 558. This is obviously not as much goldfish as you had before, so to fix this you add another tank which makes 32 tanks, but you minus 562 from 558 and you have only 4 fish in the last tank.

The formula for midpoint is

([tex]\frac{x_{1}+x_{2}}{2}[/tex], [tex]\frac{y_{1}+y_{2}}{2}[/tex])

Look at the image below to see the line segment of Estefani's (A), Jasmin's (M), and Preston's (B) houses. Keep in mind that the segment shown below is not accurate in regards to how the line segment formed by Estefani's, Jasmin's, and Preston's houses. It is simply there so you can picture the segment better.

In this case:

[tex]x_{1} =3\\x_{2} =unknown\\y_{1} =-2\\y_{2} =unknown[/tex]

^^^Plug in these number into the formula given above...

([tex]\frac{3+x}{2}[/tex], [tex]\frac{-2 + y}{2}[/tex])

To find what x is (a coordinate of Preston's house) you must take the x-value part of the midpoint equation ([tex]\frac{3+x}{2}[/tex]) and set it equal to the x-value of the midpoint (-5). Then you must solve for x:

[tex]\frac{3+x}{2}[/tex] = -5

3 + x = -5 * 2

3 + x = -10

x = -10 - 3

x = -13

To find what y is (a coordinate of Preston's house) you must take the  y-value part of the midpoint equation([tex]\frac{-2 + y}{2}[/tex]) and set it equal to the y-value of the midpoint (3). Then you must solve for y:

[tex]\frac{-2 + y}{2}[/tex] = 3

-2 + y = 3 * 2

-2 + y = 6

y = 6 + 2

y = 8

The coordinate of Preston's house is:

(-13, 8)

10 units.

Step-by-step explanation:

That would be the difference in the x coordinates as the y coordinates are both -8.

So it's 10 - 0 = 10 units.

Slope = (rise) / (run)

Rise = (171-93) = 78 ft

Run = 6.5 yards = 19.5 ft

Slope = (78 / 19.5)

Slope = 4

The correct figure is not included in the list of choices.

The slope is 4.

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

given:

roof rises= 171 feet above the ground

horizontal distance = 6.5 yards

using,

Slope = (rise) / (run)

Rise

= (171-93)

= 78 ft

Run

= 6.5 yards

= 19.5 ft

Slope

= (78 / 19.5)

Answer:

Students ticket = $4

Adult ticket = $5

Step-by-step explanation:

Let the price of the student ticket be $x and the price of a child ticket be $y.  An adult ticket costs as much as the combined cost of a student ticket and a child ticket, so the price of one adult ticket is $(x+y).

1. A movie theater advertises that a family of two adults, one student, and one child between the ages of 3 and 8 can attend a movie for $15. Then

Answer:

The expression for determining the number of distinct subsets for a set with n distinct elements is 2^n (2 raise to the power n).

Step-by-step explanation:

The expression for determining the number of distinct subsets for a set with n distinct elements is 2^n (2 raise to the power n).

If a set has 0 elements then it has 1 subset which is a null set (2^0=1)

if a set has 1 element then it has 2 subsets. One is a null set and the other one would be itself (2^1 = 1).

Like wise if a set has 5 elements then it has 32 subsets (2^5 = 32)

Lets solve an example. We have a set A and we have to find the subsets of set A.

A = {1,2,}

2^n = 2^2 = 4

It means that the number of  all the possible subsets = 4

{0},{1},{2},{1,2}....

In this exercise we have to have knowledge of sets and subsets to find the value of the unknown, like this:

[tex]2^n = 2^2=4[/tex]

So we have to remember some ideas about sets like:

[tex]2^0=1\\2^1 = 1\\2^5 = 32[/tex]

We have a set A and we have to find the subsets of set A, so that is :

[tex]A = {1,2,}\\2^n = 2^2 = 4\\A= {0},{1},{2},{1,2}....[/tex]
