Respuesta :

If you're looking for the sum, that means you're adding. So 5 books + B books would be 5 + b
So the algebraic expression would be 5 books + B = Your total.
We know that sum means adding
and we also know that we have 5 books
The thing we don't know is the number that B is
So the equation would be 5 book+ B Book= ___ Books

Hope I helped :)
