Answer 2

Translate:

    "the sum of a number and 6 is at least 15"

                    x     +             6      ≥        15

 

     x ≥ 9         [subtract 6 from both sides retains sense of inequality]

 

To check:

    Adding any number greater than or equal to 9 to the number 6 produces a result at least 15.  Any number less than 9 produces a result that is not at least 15.

Answer 3

n + 6 ≤ 15
