A water hose had filled up 1⁄3 of a pool after 1⁄2 of an hour. At this rate, how many hours would it take to fill the pool?

It takes 1.5 hours or 1 hour and 30 min. to fill the pool.
Step-by-step explanation:
3x+2y=6 -
8x+2y=2
_________
-5x=4
x=-4/5
-2.4+2y=6
y=8.4
The GCF is 2
Pull out 2 from each number:
2(2n + 5)
Hope this helps!
0.8
you find how much he needed so:
24*0.3=7.2
than 8 he had , so whats left over
8-7.2=0.8
