(1 gal, 2 qt, 3 pt) +
(1 gal, 3 qt, 7 pt) +
(1 gal, 3 qt, 3 pt)
= (3 gal, 8 qt, 13 pt)
= (3 gal, 14 qt, 1 pt)
= (6 gal, 2 qt, 1 pt)
The total volume of punch is 6 gallons, 2 quarts, 1 pint, or 6 5/8 gallons.
Answer:
Step-by-step explanation:
You need to subtract the prices of the medium and large from the total
Small = 46.24 - medium - large
17.50 + 15.75 = 33.75
S = 46.24 - 33.75
S = 12.99
Answer:
11/2
Step-by-step explanation:
5y+3=36-y
1) Subtract 3 from both sides:
5y=33-y
2) Add y to both sides:
6y=33
3) divide both sides by 6:
y=33/6
4) Simplify the fraction:
11/2
2x + 3y = 40
+
-2x + 2y = 20
___________ Adding both equations
0x + 5y = 60
____________
5y = 60
y = 60/5 = 12
y = 12.
Since we have gotten y =12, and the only option with that is option D.
So we don't have to solve for x.

Answer:
It takes 20 weeks to empty the lake
Step-by-step explanation:
Some rate, let's call it 
empties the lake in 10 weeks and a river (with rate 
can fill the lake in 20 weeks. The idea behind the solution of this type of problem is always set the rate to the same units. Let's see this:
which implies that this rate empties 0.1 of the lake per week, thus, 
.
Using the same idea, we can obtain that the filling rate of the river is:
Since both rates are acting at the same time, the total rate of flowing water (either in or out the lake) would be given by:
, which means that the lake is being empty at a rate of -0.05 week and using the rule of three:
Thus, It takes 20 weeks to empty the lake.
