Step-by-step explanation:8 days
Answer:
A. 2(x + 9) = 8
Step-by-step explanation:
To solve this problem, we proceed as follows:
- We call "x" the number picked up by Amy:

- Amy then adds 9 to this number, so we get:

- Then, we multiply this sum by 2, so we get:

- Finally, Amy says that this number is equal to 8:

So the correct equation is
A. 2(x + 9) = 8
We can even solve it to find the number. We get:

Answer: B
Because...
3x + 2x < -2x + 2x + 7
5x < 7
So you have to do addition BEFORE division.
<span>You need (8-6) 2 extra gallons to take a bath. With sixty people bathing, you'll need 60*2=120 extra gallons to meet the extra demand for water. Alternatively, you could note that 60 bathers*8 gallons per bath=480 gallons of water would be used for 60 baths and 60*6=360 needed for showers. The difference would be 480-360=120 gallons.</span>
