I think it is A. Because it says that 1/3 is dividing the difference of 15 and an number, furthermore "one third" mean divide by 3.
The correct answer is 
Write the problem in long division format,
Divide 74 by 11 to get 6,
Multiply the quotient digit (6) by the divisor 11,
Subtract 66 from 74,
Bring down the next number of the dividend,
Divide 86 by 11 to get 7,
Multiply the quotient (7) by the divisor 11,
subtract 77 from 86.
The answer is 320,000 and that’s all
Answer:
x = 14 inches
Step-by-step explanation:
The area of a square piece of paper is 200 square inches.
We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper. It is shown in the attached figure.
Area of a square = x², x is the side length

or
x = 14 inches
So, the side length of the square is 14 inches. It is shown in point A.
