Points a, b, c, and d are located on a line. a is at (-6,13), d is at (2,14), c is the midpoint of ad and b is the midpoint of ac. what is the sum of the coordinates of point b? express the answer as a common fraction.

  37/4

Step-by-step explanation:

The sum of the coordinates of point B is the weighted average of the sum of coordinates of points A and D. Those sums are A=-6+13 = 7; D=2+14=16.

Point B is 3/4 of the way from point D to point A, so the sum of its coordinates will be ...

  (3×7 +1×16)/4 = 37/4

_____

The coordinates of point B are (-4, 13.25), so their sum is 9.25 = 37/4.

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28
