One cubic foot holds 7.48 gallons of water, and 1 gallon of water weighs 8.33 pounds. How much does 8.2 cubic feet of water weigh in pounds?in tons?

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

the best estimate is 3 because   8 can only go into 24 3 times
