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>
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
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! :)

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
