You need to divide both numbers by 7 because you currently know how many gallons are pumped in 7 minutes, and we want to find out how much is pumped in one minute.
42 ÷ 7 = 6.
7 ÷ 7 = 1.
So it pumps 6 gallons per minute.
It’s not a equation it’s a formula for an equation
Plz mark me brainliest!
Hope this helps!
Value x as the weight of the large box, y as the weight of the small box
7x + 9y = 157 (1)
5x + 3y = 89 -> 15x + 9y = 267 (2)
(2) - (1) => 8x = 110
=> x = 13.75 kg
=> (1) => 5x13.75 + 3y = 89 => 3y = 20.25 => y = 6.75 kg
So, large box weigh 13.75 kg, and small box weigh 6.75 kg
Mark Brainliest if correct. :D
So he has 2/3 of the bottle left to clean 2/5 of his bathroom remaining
We have (x+12)·(x+5) = 120; where x > 0;
Then, x^2 + 17x + 60 = 120;
x^2 + 17x - 60 = 0;
The solutions are x1 = +3 and x2 = -20;
Then, x = 3 is the correct solution.
Finally, x + 12 = 15 feet (length) and x + 5 = 8 feet (width).
