    to get rid of the /4, multiply both sides by 4. after that you have \[4(\frac{r }{ 4 } \ge 12)\] the 4's cancel and leaves the 3rd option. \[r \ge48\]

    divide each side by -3. so you get \[y \le6\]

    3t < -15 t < -5 is right r/4>= 12 r >= 48 is also right -3y=< -18 however isn't y=< 6 because when you divide by a negative number you have to switch the sign around to make it y>= 6. Just for anyone finding this who may be confused by "SmithAshley" saying 2 were wrong when in fact only one was wrong.
