B is the correct answer. To find out why it is, we can simply put 2,800, the whole, as 100% and 6.2 into x=6.2. The left sides of both of them have the same units, and both right sides have the same units, so we can do something such as 2800/x=100%/6.2%. Then, you simply solve for x.
 
STEPS:
2800/x=100/6.2
<span>(2800/x)*x=(100/6.2)*x       - </span>we multiply both sides of the equation by x
<span>2800=16.129032258065*x       - </span>we divide both sides of the equation by (16.129032258065) to get x
<span>2800/16.129032258065=x </span>
<span>173.6=x </span>
<span>x=173.6</span>

The side length, s, of a cube is x – 2y. If V = s3, what is the volume of the cube? x3 – 6x2y + 12xy2 – 8y3 x3 + 6x2y + 12xy2 +
otez555 [7]

V = x³ - 6x²y + 12xy² - 8y³

V = (x - 2y)³

   = (x - 2y)(x - 2y)(x - 2y) ( expand first pair of factors )

   = (x² - 4xy + 4y²)(x - 2y) ( multiply terms in first by terms in second )

   = x³ - 4x²y + 4xy² - 2x²y + 8xy² - 8y³ ( collect like terms )

  = x³ - 6x²y + 12xy² - 8y³

You are playing a game of Scrabble and have the 5 A tiles, 3 E tiles, 1 Z tile, 2 M tiles, 3 L tiles, and 1 Y tile to choose fro
liq [111]
When reading questions like these, watch out for "or", which means to add.
There are a total of 15 tiles;
There are 5/15 (1/3 simplified) A tiles.
There are 3/15 (1/5 simplified) E tiles.
There are 1/15 Z tiles.
There are 2/15 M tiles.
There are 3/15 (1/5 simplified) L tiles.
There is 1/15 Y tiles.
We are looking for E or Y, which means we must add their fractions together.
E = 3/15, Y = 1/15.
3/15 + 1/15 = 4/15
You have a 4/15 chance of drawing an E or a Y.
I hope this helps! :)

Please help!! <br> 3.5(x) + -20 + 1/2(x) = 40 - 2x
katrin [286]
<h2>Greetings!</h2>

Answer:

x = 10

Step-by-step explanation:

First, we need to isolate all the x's on one side. To do this we need to move the -20 over to the other side making it a +20:

3.5x + 1/2x = 40 + 20 - 2x

Add the x's and the 40 and 20:

4x = 60 - 2x

Move the -2x over to the other side making it a +2x:

4x + 2x = 60

6x = 60

Divide both sides by 6:

x = 10

So x = 10
