Answer:

It would take 10 downloads

Step-by-step explanation:

Answer:

32 for Dominic and 5 for Savannah

Step-by-step explanation:

You can figure this out by first determining how many downloads Dominic has to make in order to have the total price equal to what Savannah paid just to join the club.

So Savannah paid $100 to join.  Dominic only paid $25.  So Dominic can spend $75 for downloads before he even gets up to what Savannah paid.  Now you can figure out that it will take 30 downloads at $2.50 each to get to that $75.  

You could say that Dominic is now equal to Savannah with both spending $100.  Dominic would have made 30 downloads and Savannah would have 0.  But I believe they want you to go a step further.

So now you just need to look at how many more downloads Dominic would have to make to get to an even full dollar amount.  One more download would take him up to $102.50.  A second additional download would take him to $105.  Savannah would then only have 5 downloads for a total cost of $105 and Dominic would now have a total of 32 downloads for a total of $105.

Answer:

x-4 = 7 , x-4 = -7

Step-by-step explanation:

IX - 4l+ 1 = 8

Subtract 1 from each side

IX - 4l = 8-1

IX - 4l = 7

Then separate into two equations, one positive and one negative

x-4 = 7      x-4 = -7

Answer:

The length of the window is 18 ft and its height is 14 ft

Step-by-step explanation:

System of Equations

Let's call:

L: Length of the window in feet

W: Width of the window in feet

According to the first condition of the problem:

[tex]L = W + 4\qquad\qquad [1][/tex]

The perimeter of the rectangle is 64 feet. The perimeter is calculated as:

P = 2L + 2W =64

Dividing by 2:

[tex]L + W = 32\qquad\qquad [2][/tex]

The system of equations [1] and [2] can be used to find the dimension of the window.

Substituting from [1]

W + 4 + W = 32

Simplifying:

2W = 32 - 4 =28

Solving:

W = 28/2 = 14

Using [1]:

L = 14 + 4 = 18

The length of the window is 18 ft and its height is 14 ft

Answer:

Below in bold

Step-by-step explanation:

-3(8x - 2) = 9 - 21x

~Divide -3 to everything

8x - 2 = -3 + 7x

~Add 3 to both sides

8x + 1 = 7x

~Subtract 8x to both sides

1 = -x

~Divide -1 to both sides

-1 = x

Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.

Best of Luck!

Answer:

- 1 17/36

Step-by-step explanation:

Step 1:

n - 9/4 = 2n - 7/9       Equation

Step 2:

- 9/4 = n - 7/9     Subtract n on both sides

Step 3:

- 81/36 = n - 28/36     Find common denominator

Step 4:

- 53/36 = n       Add 28/36 on both sides

Answer:

n = - 1 17/36     Convert

Hope This Helps :)

Answer:

n= -53/36

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

n+ −9/4 = 2n+ −7/9

Step 2: Subtract 2n from both sides.

n+ -9/4 −2n=2n+ −7/9−2n−n+ −9/4 = −7/9

Step 3: Add 9/4 to both sides.

−n+ −9/4+9/4=−7/9+9/4   −n=53/36

Step 4: Divide both sides by -1.

−n/-1=53/36/−1n=−53/36

Answer:Letter D.

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

subtract 7/9x -4/9x

3/9x= 1/4 +5/12

first change 1/4 to 3/12

then add 3/12 + 5/12

3/9x = 8/12

change 3/9x to 1/3x then to 4/12x

4/12x = 8/12

then mulitiply by the reciprical 12/4 on both sides

x = 2

Answer:

i  need free points, thank you

Step-by-step explanation:

Step-by-step explanation:

y varies x

y=kx

when y=5;x=6

5=6k

5/6=k

Now, when y=?;x=5

y=5\6(5)

y=25\6

y=4.17

8 inches on the map. To approach this problem, just set up a proportion:

2in =10 mi x in =40 mi.

If we use that to set up an equation we get

80 =10x.

Solve that, you get 8.

Hope this helps, let me know if you need more help.

Answer:

X=-2 (The slope is - 2/1)

Answer:

Step-by-step explanation:

(0, -9) and (3,3)

(3+9)/(3-0) = 12/3 = 4

y + 9 = 4(x - 0)

y + 9 = 4x - 0

y = 4x - 9
