Answer:
1/80
Step-by-step explanation:
-8*5*xy= -1
Sub 2 for x
-8*5*2*y= -1
-80y=-1
y=1/80
(i was kinda confused because i wasn't sure if the x was a variable or a multiplication symbol but i made it a variable) yea

Answer:
125˚
Step-by-step explanation:
The angles given are supplementary. So we can set up the equation :
(3x+5)+(x+15)=180
Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.
3(40)+5=<A
120+5=<A
<A=125
Example
if n=2
(xyz)^2=(xyz)(xyz)=xxyyzz=x^2y^2z^2
if n=4
(xyz)^4=(xyz)(xyz)(xyz)(xyz)=xxxxyyyyzzzz=x^4y^4z^4
the reason is that multiplication is associative (can move parenthasees around with multiply or add)
