Answer:
5
Step-by-step explanation:
● 2(5v+3) - 4(7v+1) = -88
● 10v + 6 - 28v - 4 = -88
● (6-4) + (10v-28v) = -88
● 2 + -18 v = -88
● -18v = -90
● v = 90/18
● v = 5
Answer:
1 hour and 7 minutes
Step-by-step explanation:
- set up two equations:
=
- cross multiply: 4.42x =294
- solve for x: 294 ÷ 4.42 = 66.52 or 67 minutes
The question is asking for hours rather than minutes so...
- 1 hour is 60 minutes
67 min - 60 min = 7 min
Therefore, it would take 1 hour and 7 minutes to fill a 294-gallon hot tub.
