<span>Nadine mixes a juice solution that is made from 3 gallons of an 80% juice solution and 1 gallon of a 20% juice solution. What is the percent concentration of the final solution? =</span>65%
Answer:
Step-by-step explanation:
- 7 + 3x - 12x = 3x + 1
- 7 - 9x = 3x + 1

- x = 6/12
- x = 1/2
It has one solution
The answer to -7 +11 -6 + 8 =6
(57-32)➗5.5 =x
The problem is just flipped.
