X=13 and z=112
you know that (13x-57) + (6x-10) = 180 since they are supplementary, so you will solve that. it will give you x=13. now that you know x, you can solve for z by plugging in 13 for x on 13(x)-57 since that and angle z are congruent. when you simplify, you will get z=112.
you can check your answer by doing (6x-10) +112=180. this is because they are supplementary. you should get x=13, and that is how you know you are right.

if you have already covered slopes, you could also get it that way, in fact is simpler that way.
Answer:
7x^2 - 2x - 3.
Step-by-step explanation:
Starts with 7x^2 then a term in x then a constant.
Answer:
"Acceleration" means any change in the speed or direction of motion ... speeding up, slowing down, or turning. So . . .
-- The distance traveled in a certain time may increase or decrease.
-- The displacement covered in a certain time may increase or decrease.
-- The speed of the object may increase or decrease.
-- The velocity of the object (speed/direction) will change.

Pido perdón para mí español, pero creo que este es la ecuación.
