3 n + 4 ≥ 9 3 n + ( 4 − 4 ) ≥ ( 9 − 4 ) 3 n ≥ 5 3 n ( 3 ) ≥ 5 ( 3 ) n ≥ 15
The question involves translating a verbal inequality into a mathematical one, resulting in the expression x/3 + 4 ≥ 9, which simplifies to x ≥ 15. ;
To represent the statement 'Four more than the quotient of a number and three is at least nine,' we set up the inequality 3 n + 4 ≥ 9 . Solving it leads to the result that the number n must be at least 15.
