5/$3.00 is the unit rate. Hope it helps!
By cross-multiplying, we get
15x + 30 = 24
15x = -6
x = -3 / 5
The easiest way to determine the answer is to just divide $57/$60 = 0.95 or 95%
Okay. I am guessing that you are asking for the amount of water poured per minute. The bathtub already holds 12 gallons and 32 - 12 is 20. The tub is full in 5 minutes. Let’s divide. 20/5 is 4. There are 4 gallons of water filled in the tub per minute.
If the two lengths of the triangle are 2x+6 and x-1
(2x+5)+(x-1)=3x+4
(10x+2)-(3x+4)= 7x-2
