Six more than the quotient of four and a number x

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.

*segment an is an altitude of right ? abc with a right angle at a. if ab = 2root 5 in and nc = 1 in, find bn, an, ac.
