I have a white SG roo on the way and a black silkie hen. If I put them together what will I get? will it be a mix of SG and silkies, blues maybe??? I am really new at this, sorry...
SG plus silkie would make...

What is an SG?
show girl... depends what's hidden under your white.
White as in white SG is not same as a white out of blue mating. The "whites" of blue matings are Splash. Quite variable, basic color is pale grey with blue/black random speckles.
Think of white as a white lab overcoat. Wear it over your(colored) shirt and pants. So white is just something that prevents whatever color/pattern the bird has from showing. Could be black, blue, partridge.....
Parts of your question can be answered- white in silkies is recessive plus black is dominant so probably expect mostly or even all black chicks. There's always surprises though due to the white hiding whatever colors plus the black might happen to be a carrier for white so half of the chicks could be white. Just something you won't know for sure until eggs are hatched.
If the roo is not pure for naked neck, half of the chicks will have naked necks.. if he is pure for naked neck then all will be SG.

Dominant/recessive refers to the relationship between the different alleles of a gene, not the relationship between different genes.
With recessive white, the allele that causes the bird to be white is recessive to the allele that does not cause the bird to be white. A bird can be (c,c), (C,c) or (C,C). The only one of these gene pairs that causes the bird to be white is (c,c).
All birds carry 2 copies of every gene (with the exception of sex-linked genes), and unless hidden by some other gene (such as recessive white) will show up in the appearance of the bird.
Black and blue are separate genes. The blue gene will, however, turn a black bird into a blue bird, so the black cannot provide the gene for blue offspring--it must come from the other parent. It is possible that the white is hiding blue, but don't expect it. More times than not it will not be there.
Partridge is a strong likelihood because silkies have an e^b base and Pg is very common in silkies, regardless of variety.

If the showgirl has a bowtie, he is het for na; half his offspring will be silkie, not showgirl. If he has a completely naked neck, then all his offspring will receive a gene and be showgirls with a bowtie when bred to a silkie.
Make that Na, not na

oh boy I am usually a smart girl but I am so confused by these genes and breeding.
In laymens tems My white SG roo and Black silkie hen will probably hatch both sg and silkies and the colors can be just about anything? and the sg will have the bow tie because it is not SG on SG (that is if my sg has a completely naken neck which I believe it does) and that the I will likely get mostly partridge color and black
is that right??? Sorry if I sound like a total idiot.

If your showgirl has a completely naked neck, then he is homozygous for the naked neck gene and all his offspring will receive one copy of the naked neck gene from him. If he is bred to a silkie, then all the offspring will have only the one copy and will be naked neck with a bowtie.
If bred to another showgirl who has a completely naked neck, then all their offspring will have completely naked necks.
If bred to a showgirl with a bowtie, then half their ofspring will be completely naked neked and half will have the bowtie.
Now, if you showgirl has the bowtie, half his offspring will have the bowtie and the other half will be silkie with fully feathered necks.
Now for colours. If you breed a white to a white you should get all whites. If you breed a white to anything else, it is impossible to determine the colour of the offspring. One can speculate, but that is no guarantee of anything. My speculations were very general, and may or may not match what your birds will produce.
Once you've done some test breeding with a particular white, you can make come informed speculation for that particular bird, based upon previous results--but those will not necessarily hold true for a different white.

Hmmmn.
I have to read all this again later, when my cold medicine wears off....
I have the same questions, but the answers are currently going in circles in my head
