or he.
hartnn (hartnn):
if B is the mid-point
AB=BC
10=2x+5
can u find x from here ?
OpenStudy (anonymous):
lol, my bad. didn't read the question properly.
OpenStudy (anonymous):
5=2x ?
OpenStudy (anonymous):
therefore x = ?

2x=5
x=5/2
ok?
OpenStudy (anonymous):
ohhhhh....
OpenStudy (anonymous):
so b will be the midpoint right.

hartnn (hartnn):
wait, we need to check that.
if B is midpoint.
AC=2AB
5x=2(10)
can u find x from here ?
OpenStudy (anonymous):
x=5
hartnn (hartnn):
sure ?
OpenStudy (anonymous):
so now what ?

what... am confused
hartnn (hartnn):
5x=2(10)
5x=20
x=4
ok?
OpenStudy (anonymous):
now is point the midpoint
hartnn (hartnn):
since 2 values of x DO NOT MATCH.(4 and 5/2)
B cannot be the mid-point.
hartnn (hartnn):
did u get that^ ? @lvasquev462
