Let

be the length of the side of the hot tub. Ricardo wants the pool's sides to be 5 times as long, so
Answer:
F (4h>18)
How To Do It:
She's walking at a rate of 4 miles per hour. Which means that you would be multiplying 4 by the amount of hours Liang walks(4h). The next part of the inequality is the sign and the other value. To get this from the equation we see that it says she must walk at least 18 miles. Meaning that the 4h will always be greater than the 18 that is on the other side.
Answer:
see below
Step-by-step explanation:
First line:
y = mx+b where m is the slope and b is the y intercept
y = 2x + 10
Second line
y = mx+b
y = 3x+0 since there are no barrels filled on this line when they flip the switch
Setting the two equations equal
2x+10 = 3x
Subtract 2x from each side
2x+10-2x= 3x-2x
10 = x
Each line will have filled 10 barrels when they numbers are equal.
