Y = 1/2x+5 I think that’s it
Do 19 divided by 1.5 and you get 12.6666667 repeating. But she needs about 12 cups
The ratio of x:y:z = 20:8:11
Total unit = 20+8+11 = 39
Value of 1 unit ratio = 78/39 = 2
So, the water in container X, 20(2) = 40 liters
Your answer is 40 liters
2/21 is the answer.
1/3+4/7=19/21
Hope this helps!
