(10x-20)= (6x+8) subtract 6 from each side
(4x-20)=(+8) add 20 to each side
(4x)=(28) divide both sides by 4
x= 7
So you basically have to find the area as if it were a rectangle, which would be 19*13, which is 247. Then, you find the area of the corner taken out and subrtact it, so 3*4 is 12, and 247-12 is 235.
Answer:
15 gallons each minute, 180 gallons left after 8 min
Step-by-step explanation:
Divide 300 by 20 to get over minute
