Answer: okay sure!
Step-by-step explanation:
In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it.
The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Answer:
7
Step-by-step explanation:
15+-8=7
8) you go up by 2 on the y-axis and over 3 on the x-axis
9) you have to go up 3 on the y-axis and over 2 on the x-axis
But you always have to go over then up
I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.

Answer:
0.69
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the sine is the ratio ...
Sin = Opposite/Hypotenuse
For angle P, the opposite side is OQ. The hypotenuse is the longest side, PO. So, the sine is ...
sin(P) = OQ/PO = 20/29
sin(P) ≈ 0.69
