7 quarts because 1 gallon is 4 quarts so 4•3=12 and 12-5=7 (Brainliest please)
I believe the answer would be 2 of 120
Answer:
26.25 gallons
Step-by-step explanation:

21000 = 800x
x = 26.25 gallons
This is true, because the LSRL does get its line when minimizing the sum of the squares difference between the observed (x value) and predicted (y-at)
Cross multiply:
2.5 ft x 16.5 ft = 41.25 ft
now divide:
41.25 / 8.25 = 5
L = 5 feet
