Answer:
x=6
Step-by-step explanation:
5x-3=2x+15
5x-2x-3=15
3x-3=15
3x=15+3
3x=18
x=18/3
x=6
there are 6+9+10=25 equal parts, so Ben has 9/25 of the total.
Equations:
x + y = 26
x - y = 4
---
Add to get:
2x = 30
x = 15

Solve for "y":
x + y = 26
15 + y = 26
y = 11 (smaller number)

20 gallons of water is leaked after an hour.
Step-by-step explanation:
Water is leaking at a constant rate of 1/3 gallon per minute.
a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.
So, the equation is
......... (1) (Answer)
b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write
gallons.
Therefore, 20 gallons of water is leaked after an hour. (Answer)
