(8,8)? I believe sorry if wrong

Answer: (8,8)

Step-by-step explanation:

First you need to get a x or y by itself.

I choosed to get y by itself since it would be faster.

-2x + y = -8  (first get -2x to the other side so add 2x)

y = -8 + 2x (then you want to insert that to the other equation)

-x + 4( -8 +2x) = 24      ->    -x -32 + 8x = 24   ->   7x -32 = 24

(add 32 to the other side)

7x = 56 (divide 7 to 56 to get x) x = 8

now insert into the other equation

-2( 8 ) + y = -8     ->     -16 + y = -8 ( move -16 to the other side, so add 16)

then you get your answer, y= 8

Leigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1
aleksley [76]
20/3 - Take the 6 2/3, multiply the 6 and the 3 (6 x 3 = 18), then add the 2 (18 + 2 = 20). Put that number over the original 3 and you've got yourself a mixed number.

Sunny_sXe [5.5K]

Answer: x=5

Step-by-step explanation:

Substitute 17 for n(x)

17=2x+7

Subtract 7 from both sides

10=2x

Divide each side by 2 to get the x by itself

x=5

I need help with this!
sashaice [31]

Answer:

Step-by-step explanation:

Let the width be w centimeters.

Then the length = w + 7.

The area A is found from the length multiplied by the width.

330 = w(w + 7) = w^2 + 7w.

Now we can rearrange this equation to form a quadratic, as follows:

The factorization of the quadratic is:

(w + 22)(w - 15) = 0

Therefore we find that:

width = 15 centimeters

length = 22 centimeters
