Answer:
y = 15x
0=0, 1=15, 2=30, 3=45, 4=60, 5=75, 6=90
Step-by-step explanation:
180/12 = 15 ft/s
Therefore, every second, the balloon rises 15 feet.
I think 2.20e23 because it said bodies not body
80 and 20
80+80+20=180
5x - 6y = -90
-10 x - 6y = -90
Subtracting,
15x = 0
x = 0
y = -90/(-6) = 15
Answer: x=0, y=15
