Find the value of x.
A line segment is shown with endpoints labeled A and N and a point in the middle of the line labeled M. Segment AM is labeled as 7 x plus 0.1. Segment MN is labeled as 10 x minus 0.2. Line segment AN is labeled as 5.
A. 2.8
B. 1.7
C. 0.3
D. 0.1

B. 1.7
Wrong again!
It said M is "in the middle of the line" so AM = AN
7x + .1 = 5
7x = 4.9
x = 4.9/7 = .7
so AM = 7x + .1 = 4.9 + .1 = 5 , looks good, since AM = AN
and that would make MN = 10
but we are told 10x - .2
= 7 - .2 = 6.8
So there is a contradiction in the problem, and it is bogus
btw, there was no question asked, and how the "robot" got 1.7 is beyond me.

This AI lacks intelligence. It is driving me up the wall.
I think "middle" is misleading. I suspect they mean somewhere between.
If so
7x +.1 + 10 x - .2 = 5
17 x = 5.1
x = 5.1 / 17 = 0.3
AM =2.4
MN = 2.8
If so
7x +.1 + 10 x - .2 = 5
17 x = 5.1
x = 5.1 / 17 = 0.3
AM =2.4
MN = 2.8
I mean AM = 2.2
