Explanation:Which
sentence from the passage shows that the function of the river depicted here has carried through to modern times?
Answer: x= 75
Explanation:1x -3y = 30
And y = 15
Substitute y accordingly into the equation, so that
x - 3(15) = 30
x-45=30
Add 45 to both sides if the equation
x-45+45=30+45
x=75
Answer:
9800 J
Explanation:
P.E = mgh
- m = mass
- g = gravitational acceleration
- h = height
P.E = (10.0)(9.8)(100) = 9800 J
