Adult Flim Even Though I'm A Minor Can I Get Into An R Film W/o An Adult?

Even though I'm a minor can I get into an R film w/o an adult? - adult flim

My bf and I would like to see 2marrow Friday the 13th, but we're only 15 and can not see a rated R Flim.
So he goes and Cinemark have to buy my mother and then the edge off for me and only with the contributions go. Is it still id-ED, if we walk in?
Can we?
