How can I change a +/- 5V Sine Wave to a (0 to 5V) signal for an ADC
This is very easy:



R1 and R2 must be equal in your case.  The overall values of R1 and R2 depend on things you haven't told us, like the source impedance and the maximum allowed impedance of OUT.  If OUT is a signal going into something like a microcontroller A/D, then start with 10 k&Omega; for R1 and R2.

A better answer will require a better question.
