Answer:
15y
Step-by-step explanation:
first the 2 can cancel:

turns into:

now since we need to find x-y,
x=16y
16y-y=15y
I might come back to this because I'm not 100% sure this is the answer you are looking for. Let me know if you have any questions.
Answer:
the answer is a 20% increase
Step-by-step explanation:
first, you have to find the amount of change (how much her points scored increased
second , you would divide
which equals 0.2
then you would multiply by 100 or move the decimal two places to the right
which would equal 20%
Answer:
576 cm^3
Step-by-step explanation:
Express this volume formula as V = π r^2 h, where the " ^ " symbol indicates exponentiation. Substitute 4 for r (this is half the diameter), 12 cm for h, and 3 for π: V = 3*(4)^2*12 cm^3, or V = 576 cm^3.
The answer is 1/20. This is probability. <u><em>probability is the chance of you picking a certain thing</em></u>. for example: You have 3 blue marbles, 6 red marbles, and 4 purple marbles. the probability of pick a blue marble is 3/13. A red would be 6/13, and a purple would be 4/13.
So what this is asking is what are the chances that something will happen over something will not happen. the said that "the probability that an event will not happen is P(E') = 19/20. if you are having a lot of trouble with this, try removing the events with something like marbles (Something you have done before) this tends to make it a little easier to read.
<span>Simplifying
3x + -1y = 12
Solving
3x + -1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
3x + -1y + y = 12 + y
Combine like terms: -1y + y = 0
3x + 0 = 12 + y
3x = 12 + y
Divide each side by '3'.
x = 4 + 0.3333333333y
Simplifying
x = 4 + 0.3333333333y</span>
