    r<=-2

    Step-by-step explanation:

    -3 (r-5) + 7>=28

    Distribute

    -3r+15+7>=28

    Then add like numbers

    -3r+22>=28

    subtract 22 from both sides

    -3r>=6

    Divide and when you divide/multiply a negative you flip the inequality sign

    r<=-2

    r≤-2

    Step-by-step explanation:

    -3 (r-5) + 7≥28

    simplify

    -3r+22≥28

    subracts by 22 on each side

    -3r≥6

    divide by - 3, dividing by a negative switches the sign

    r≤-2
