1> which expression represents "5 less than the product of 7 and x"?
is the answer this: 5-7x
2> can anyone give me an example of multiplicative inverse property?
Common sense tells me that the first one should read 7x-5. 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
