Why is “x” used as an abbreviation for some nouns?

This question is related, but is not a duplicate, of Why do some words have "X" as a substitute?.

I have noticed that a few nouns can be significantly abbreviated with an "x" at the end. Some examples come to mind:

Transmit → Tx

Receive → Rx

Passengers → Pax

Tickets → Tix

There are likely others in existence I'm not aware of. Most abbreviated nouns ending in "x" seem to be used only as technical jargon (in this case, Fax, Fax, Transportation, Entertainment, respectively). What is the history of using "x" at the end of a word to severely shorten it? And, does the usage of "x" in this context have a single word to describe it?

In these cases X marks an abbreviation. Passengers becomes PAX, transmission becomes TX and so on.

This method of abbreviation for Passengers existed in the 1940s according to the comments in another article at this site: What does "pax" mean in the context of the apartment rental?.
