Use easy numbers if you get confused on problems like these.
I'm going to use 12 instead of c.
Since you have 12 pieces of candy and 6 friends, each friend would get 2 pieces, because 12/6=2.
Now, substitute c for 12, and you get c/6.
Hope this helps!
True.
For a triangle to have one interior (closed figure), the sum of two of its sides has to be greater than the other side. This rule applies to every combination of the triangle. 8+1=9, which is greater than 8. 8+8=16, which is greater than 1. Since every combination works, these segments can form a triangle.
