The closest you can get to a 2/3rds decimal is 0.66 and that goes to infinity.
It is a never ending decimal.
4) The line segments formed are parallel because they never meet.
8) The answer is B. That is because there is a right angle and right angles are formed by perpendicular lines.
Hope this helps :)<span />
10x = 4(2x -9)
10x = 8x - 36
10x - 8x = -36 - 8x
2x = -36
2x ÷ 2 = -36 ÷ 2
x = -18
If you need a better explanation just as in the comments.
