It should be D: 35. 14 + 6 = 20. I just multiplied that by two, which equals 40. That means there are 2 sets of 14 and 2 sets of 6. Since there is 10 leftover, I divided both by 2. 7 + 3 = 10. 14 x 2 = 28 + 7 = 35
Answer:
4 hours and 24 minutes
Step-by-step explanation:
Holy moly macaroni what in the world
This system has exactly one solution, because the two equation are linearly independent (i.e. one is not a multiple of the other).
We can explicitly find the solutions: from the first equation we deduce

Plug this value for x in the second equation:

Multiply both sides by 6 to get

Plug this value for y in the expression for x:

Since both a,b are not zero, both solutions are well defined.
