1> which expression represents "5 less than the product of 7 and x"?
is the answer this: 57x
2> can anyone give me an example of multiplicative inverse property?

Common sense tells me that the first one should read 7x5. You have it reversed.
Your second question should be answered in here somewhere:

A math tutor should be along soon to give you further ideas.

Yours would be right if it read 5 less seven times x. But it does not say that. See Writeteachers comment.
For any number n, there exists a number 1/n such that n* 1/n=1
example: Find the multiplicative inverse of 7.93
7.93 ( MI)=1
MI=1/7.93= .126103405...
