A permutation, since once you choose one member to be in the team, that same person cannot be chosen again. A combination requires us to be able to freely choose the same item in a set as many times as we may wish. A permutation restricts the amount of times we can choose an item in a set.
Answer:
AC = 6 ÷ 7
x = 2
Step-by-step explanation:
Given that
AB = 5x - 2
BC = 9x - 10
So,
AC = AB + BC
= 5x - 2 + 9x - 10
14x -12 = 0
AC = 6 ÷ 7
As B is the mid point of point A and point C, so the value of x is determined by solving the given equations mentioned in the question
5x - 2 = 9x - 10
5x - 9x = -10 +2
-4x = -8
x = 2
Hence, the value of AC and the X is 6 ÷ 7 and 2 respectively
