Let me know if you need any clarification as to how I got those answers. They should be self-explanatory but I'm happy to clarify further if needed.
I think the answer is 12.8 mm
It is systems of equations.
Let cups=c and l=liters
7c + 3l = 9.8
<span>5l - 9c = 6 </span>
<span>35c + 15l = 49 </span>
<span>15l - 27c = 18 </span>
<span>62c = 31 </span>
<span>c = 1/2 pint </span>
<span>l = 2.1 pint </span>
<span>1 cup = 1/2 pint 1 liter = 2.1 pints</span>
