Three fourths of a number decreased by nine is at least forty-two. as an inequality.

Answer

x ≥ 68

Explanation

let that number be x.

(3/4) of x = (3/4) × x

                = 3x/4

Decrease 3x/4 by 9,

3x/4 - 9

This expression is at least 42,

∴ 3x/4 - 9  ≥ 42

   3x - 36 ≥ 168

    3x ≥ 168 + 36

    3x ≥ 204

      x ≥ 68
