Solve the inequality - 3 (r-5) + 7≥28.

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
