Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.

Ricardo has <u>16</u><u> golf balls</u>, to begin with. He started out with 16, and lost 6, 16 - 6 = 10. He bought 12 golf balls, 10 + 12 = 22. He lost 4 golf balls, 22 - 4 = 18. So in the end, he has 18.
The equation I would use is (2/3)*2 which equals 1.33. Thats how much she would throw out though. So then you'd have to do 2-1.33 which means she would have about 0.67 US gallons. (I rounded the numbers, for more accurate leave them repeating)
