Answer:
N = 30 degrees
Step-by-step explanation:
You add 60 and 90 and you subtract your sum from 180.
Answer:
1) 3,6,9
2) the pattern will keep growing around 3 multiple
3) the next pattern is 12,15
(3)(-5x+y=-3)
(5)(3x-8y=24)
-15x+3y=-9
15x-40y=120
3y=-9
-40y=120
-37y=111
Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5
Hope, this helps.
