Answer:
x <5
Step-by-step explanation:
2(4 x + 3) < 5 x + 21
Distribute
8x +6 < 5x +21
Subtract 5x from each side
8x -5x +6 < 5x-5x+21
3x +6 < 21
Subtract 6 from each side
3x+6-6 <21-6
3x <15
Divide each side by 3
3x/3 <15/3
k = 29 i think tho
5k - 3 + 9 + k = 180
6k + 6 = 180
6k = 174
k = 29
30 days (do correct me if I'm wrong haha)
5 gallons = 2 days
