Answer:
C. The sum of 18 and half the product of 9 and 4.
.57 I would assume but it really depends on how your scaling it
Answer:
x= -
Step-by-step explanation:
First move the x on the right side the the left side. Now your equation is
2x+
=
Next move 1/2 to the right side. Now your equation is 4x=
. Next divide both sides by 4 to isolate "x." Now your equation is x= -
Hope this helped and have a great day.

Answer:
<em>Pool 1 leaks faster than pool 2.</em>
Step-by-step explanation:
<u>Rates of change</u>
The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.
We are given two rates of change for two pools that are leaking. The first one loses 2/3 gallon in 15 minutes, and the other loses 3/4 gallon in 20 minutes.
To compare them, we are required to express time in hours. Recall one hour has 60 minutes, or equivalently, one minute has 1/60 hours. Converting both times, we have:
15 minutes = 15/60 = 1/4 hours
20 minutes = 20/60 = 1/3 hours
Now compute both rates of change:
Pool 1:

Pool 2:

Comparing both ratios, it's clear pool 1 leaks faster than pool 2.
