The mode is a number that is repeated the most, so if there is 3 numbers, the "mode number" has to be repeated twice or three times.
A) since 1 is the mode, two of the numbers are 1, the last number is
15 -1 -1 = 13 <em> </em><em> the three numbers are 1, 1, and 13</em><em />.
B) since 5 is the mode, two of the numbers are 5, the last number is
11 -5 -5 = 1 <em> </em><em> the three numbers are 5, 5, and 1</em><em />.
Range is when you subtract the smallest number to the biggest number, so 5-1=4 <em>The answer is 4</em>
For this case we have the following system of equations:

We solve by the matching method.
Matching we have:

Thus, the solution of the system is given by:

Answer:
You want 40% of 140 gallons to be methane,
so 60% of 140 gallons is water
methane: 0.4(140) = 56 gallons
water: 0.6(140) = 84 gallons
