Answer:
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.
Subtract 11 from 9 and get -2 so x=-2
Answer: 4.5
Step-by-step explanation:
9/2
is already in the simplest form. It can be written as 4.5 in decimal form (rounded to 6 decimal places).
