Answer:
x = -2
y = 7
Step-by-step explanation:
x = 12 - 2y
7(12 - 2y) + 4y = 14
84 - 14y + 4y = 14
84 - 10y = 14
10y = 70
y = 7
x = 12 - 2 x 7
x = 12 - 14
x = -2
50 km/h = 4 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours

H=1in
You would need to use the equation V= pie times radius squared times height. Since it gives you the diameter, you would need to divide 3 by 2 to get 1.5. So now you would plug in 7.1=pie×1.5(squared)×h
Now solve the equation to get 1in.
And you can check this answer by using this same equation to plug in pi×1.5 (squared)×1 and you will get 7.1 as your volume.
Ed because 2 and 8 are equal
