Answer is B. (x-6) +5
Let's analyze the expression "five more than the quantity of a number minus six".
"five more than the __"
Well you know just from this statement "five more than" that whatever comes next, + 5 will have to come after it.
"the quantity of a number minus six"
When a problem does not give an exact amount or quantity of a number, you would just assume it is represented as X. So whatever X is, you must minus 6 from it and then add 5 to that difference.
