A straight line is equal to 180, anything going all around is 360 if the angles are crossing eachother then the angles across from eachother are equal so x=z
X+150=180, Im not good at explaining sorry, but i know what I’m doing yk just lmk sorry if it didn’t help
I believe not? I’m sooo sorry if it’s wrong

Step-by-step explanation:
1/5 x^2y - 1 2/3 y^2 x + 4 4/5 yx^2 - 1/3 xy^2
I will write the x and y terms in order for x and y
1/5 x^2y - 1 2/3 xy^2 + 4 4/5 x^2y - 1/3 xy^2
This way I can put the like terms together
1/5 x^2y + 4 4/5 x^2y- 1 2/3 xy^2 - 1/3 xy^2
Combine like terms
(1/5 + 4 4/5) x^2y - (1 2/3 + 1/3) xy^2
5 x^2 y - 2 xy^2
We know x =-2 and y = 1/2
5 ( -2)^2 (1/2) -2(-2) (1/2)^2
Calculating the powers first
5(4) (1/2) - 2(-2) (1/4)
10 - (-1)
10+1

For the first one it would be:
C(800)=600
The second would be:
C(200)=e
And the third would be:
C(s)=900
2 and 14/15
Because the first step of subtraction is common denominators
