Answer:
3
Step-by-step explanation:
if you plug in 3 for x, it becomes 2(3)-7=-1
then 6-7=-1
-1=-1
<span>14+ 9 + 2+ 13+ 16+3+ 13+ 10 = 80
80/8 = 10
answer
mean = 10

<span>Let x=amount of time it takes both pipes draining together to empty the pool
First pipe empties at the rate of 540,000/150=3600 liters/min
Second pipe empties at the rate of 540,000/225=2400 liters/min
Together, both pipes empties at the rate of 3600+2400=6000 liters/min, so our equation to solve is:
6000*x=540000 </span>
Well we know that it grows 8 in a year. so after 1 year has grown 1 * 8 and after 2 years 2 * 8 and after 3 years 3 * 8 and so on. since x is the year we can say 8x. but it starts with 5 ft so we add in the 5 to get h.
h = 8x + 5
