Answer:
Step-by-step explanation:
Let the number at B be x.
We know that distance between two points on the number line is the absolute value of the difference of numbers at those points.
Then distances representing the lengths of segments AB and BC are:
We are given the ratio of segments:
Substitute and solve for x:
- (x - 9)/(13 - x) = 2/3
- 3(x - 9) = 2(13 - x)
- 3x - 27 = 26 - 2x
- 3x + 2x = 26 + 27
- 5x = 53
- x = 53/5
- x = 10.6

If n is a negative number, x would be less than -8.
B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
