Answer: -82y
-70y - 20z + 4z + 16z - 12y
-82y + 0
= -82y
Answer:
4 meters.
Step-by-step explanation:
We have been given that a mover uses a ramp to pull a 1000 n cart up-to the floor 0.8 meters high. It takes a force of 200 newtons to pull the cart. We are asked to find the length of the ramp.
We will use following formula to answer our given problem.
Therefore, the length of the ramp would be 4 meters.
Answer:
5!
Step-by-step explanation:
-40÷5 = -8
The slope m=(y2-y1)/(x2-x1)
m=(8-4)/(5-1)
m=4/4=1
now let s solve the constant b
y=x+b
8=5+b
8-5=b
3=b
now we know the slope m=1 and the constant b=3
let s write the equation is
y=x+3 <--------- Final answer
You see you can break it up by 30's, 30 is its greatest common factor, so 30 can go into 90 3 times and 120 4 times so it turns to= 3/4
