distribute
-3y -9 = 2y+3
add 3y to each side
-9 = 5y +3
subtract 3 from each side
-12 = 5y
divide by 5
-12/5 = y
y = -2 2/5
To be a triangle
1)sum of two sides should be more than 3d side,
2) 3d side should be more than difference of two other sides.
5+13 > x, ----> x < 18
13 - 5 < x, -----> x > 8
8< x < 18
It looks like only one value of the side can create a triangle,

Step-by-step explanation:
The volume after 30 minutes is:
(4.5 gal/min) (30 min) + 115 gal = 250 gal
