Answer:
X + Y - W - Z = 180
Step-by-step explanation:
In parallel lines If you use the rules of:
* Alternate angles are equal
* Linear Pair Angles supplement to 180
And use the picture below for calculating the result: finally we get
Z = Y - (180 - (X - W)) which becomes the answer above if you simplify the parentheses.
Trey will read 18 pages in 45 minutes.
This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18
Simplify 6 – 4x – 2 + x
Combine like terms:
6 - 2 = 4
-4x + x = -3x
-3x + 4, or (A) is your answer

Simplify 5 – 2x – 3 + x
Combine like terms:
5 - 3 = 2
-2x + x = -x
-x + 2, or (B) is your answer

hope this helps
