Answer:
Option D) x = 2
Step-by-step explanation:
(4-2)(x-2) = 4x - 8
Distribute and simplify 4-2
2(x-2) = 4x - 8
2x-4 = 4x -8
Subtract 2x on both sides and add 8 on both sies
4x - 8 = 2x-4
2x= 4
Divide 2 on both sides
x = 2

Add all the numbers together:
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10= 136
divide the total with the total amount of numbers
136/17 = 8
Now add all the numbers again WITH the one
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10 + 1= 137
Divide the total amount with the amount of numbers there are
137/18 = 7.61
7.61 < 8
