Sue claims that the solution to the equation 12x-3(5+4x)=7x+20 is x =-5 she shows the steps below to justify her solution

Not exactly sure lol

Answer:

120 cubes

Step-by-step explanation:

first you find the volume of the rectangle: 2*5/3*4/3=40/9

then find the volume of the cube: 1/3*1/3*1/3=1/27

(40/9)/(1/27)=120

Answer:

1) 9(x - 3) = 9x - 27. So, 1) applies.

2) 3(3x - 9) = 9x - 27. So, 2) applies.

3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.

4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

Step-by-step explanation:

1) 9(x - 3) = 9x - 27. So, 1) applies.

2) 3(3x - 9) = 9x - 27. So, 2) applies.

3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.

4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

The expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:

9(x - 3):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

3(3x - 9):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

x(9x - 3):

Expanding the expression, we get 9x² - 3x.

This expression is NOT equivalent to 9x - 27.

3(3x - 7):

Expanding the expression, we get 9x - 21.

This expression is NOT equivalent to 9x - 27.

3(x - 9):

Expanding the expression, we get 3x - 27.

This expression is NOT equivalent to 9x - 27.

Therefore, the expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

So, the correct options are 1 and 2.

Answer:

4 12/18, simplified is 4 6/9

Step-by-step explanation:

You change the fractions to improper fractions so 10 1/2 to 21/2 and 2 1/4 to 9/4. Since we can't divide, we change 9/4 to 4/9 and multiply. 21 times 4 is 84 and 2 times 9  is 18.  Since that is an improper fraction, we have to change it to a mixed number. 18 can go into 84 4 times, and 18 x 4 is 72. 84 minus 72 is 12 so the final answer is 4 12/18 (simplified 4 6/9)

Answer:

[tex]y = 5(6) {}^{x} [/tex]

Step-by-step explanation:

A exponential function is represented by

[tex]y = ab {}^{x} [/tex]

where a is the vertical stretch and b is the base and x is the nth

power of x

Since the first number corresponds with zero, that means our y intercept is the first number.

This means when x=0 , y=5 so let find the value of 5.

[tex]5 = ab {}^{0} [/tex]

b to the 0th power equal 1 so

[tex]5 = a \times 1[/tex]

[tex]a = 5[/tex]

Our equation is for now

[tex]y = 5b {}^{x} [/tex]

Now let plug in 1,30

[tex]30 = 5b {}^{1} [/tex]

Divide 5 by both sides

[tex]6 = b {}^{1} [/tex]

Anything to the 1st power is itself so b equal 6.

So our equation is

[tex]y = 5(6) {}^{x} [/tex]

Answer:

x = fiction books

3x = nonfiction books

x + 3x = 2000

After you solve for x, (which is the number of fiction books), you can plug its value into the equation for nonfiction books (3x) and that will give you the number of non fiction books.

Answer:

28

Step-by-step explanation:

Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:

28x + 24y = 1,188

28x + 13y = 836

So since the number before the x is the same in both equations, we are going to want to cancel that out.

28x + 24y = 1,188

-1(28x + 13y = 836)

----------------

28x + 24y = 1,188

-28x - 13y = -836

Add the two equations together! There will be no x value :)

11y = 352

y = 32... The deluxe basket is going to cost $32

Put the y value into one of the equations to solve for x.

28x + 13(32) = 836

28x + 416 = 836

28x = 420

x = 15... The regular basket will cost $15

Hope this helps!
