Question 785486: On a number line, point B is two-thirds the distance from point A to point C and is located at -5. If A is at -11, what is the greatest possible coordinate of point C?
A)-20
B)-2
C)-1
D)4
Please explain with steps I'm new to geometry and its hard!

You can put this solution on YOUR website! On a number line, point B is two-thirds the distance from point A to point C and is located at -5. If A is at -11, what is the greatest possible coordinate of point C?
---------
Draw the picture:::
A.............B......C
-11...........-5.....?
==================
From -11 to -5 is |-11--5| = |-11+5| = |-6| = 6 units
----
Equation:
(2/3)(A to C) = 6
A to C = (3/2)6
A to C = 9 units
----
The coordinate of C is -2
