Sorry for the dumb question, but I have a 700x35c Matrix wheel and I want to replace the tires. One Kenda tire is listed as a 700x37 and in the next paragraph as a 700cx35. The "c" seems to be missing and sometimes moves.

It'll work just fine. The 35 vs 37 just means that the tire is theoretically 2mm narrower. 2mm isn't very much and, in real life, it might not be any different at all. The "c" is a rim size measurement like in shoes. Size "c" is so common, and the others are so rare, that the c is often omitted.
