Answer:
- Bottle of water = $2
- Bottle of grape juice = $1.50
Step-by-step explanation:
<u>Equations:</u>
- 3g + 5w = 14.50
- 2g + 3w = 9.00
<u>Subtract the 3 times the second equation from the twice the first:</u>
- 2*(3g + 5w) - 3(2g + 3w) = 2*14.50 - 3*9.00
- 6g + 10w - 6g - 9w = 29 - 27
- w = 2
<u>Then, finding g:</u>
- 3g + 2*5= 14.50
- 3g = 14.50 - 10
- 3g = 4.5
- g = 1.50
Y=-2/3 + x/3......................
Answer:
47x - 28
Step-by-step explanation:
10x + 2 + 27x - 28
20x + 27x - 28
47x - 28
It would take her 10 hours. If it is double the time for one person to complete the task versus two, you can guess that the other person takes the same amount of time
