Okay, so it might be a little difficult to explain it but here we go:
You find the LCD (lowest common denominator) and multiply the top and bottom half of the fraction by the LCD:
(1/x) times xy (since it is divisible by both x and y)
then you do the same for the bottom (2/y) times xy
The x's on the top cancel out leaving you with 1/y
The y's on the bottom cancel out leaving you with 2/x
So now you multiple the top half (numerator) by the reciprocal of the denominator. In other words, multiply (1/y) by (x/2).
The answer is x/2y
Answer:
B
Step-by-step explanation:
You simplify it using radicals.
Answer:
Step-by-step explanation:
First, distribute the -2 to the rest of the parenthesis, following PEMDAS.
Then, add -6a to both sides.
Now, you can divide both sides by 2 to isolate b.
Divide to simplify.
Answer:
10 feet.
Step-by-step explanation:
I am assuming this is a right triangle. We use Pythagoras theorem:
h^2 = 6^2 + 8^2
h^2 = 100
h = 10 feet.
