Answer:

Step-by-step explanation:

Here you go

  • Use PEMDAS

Step 1

-1 (r-3) ≥ 3(r + 5)  Question

Step 2

-1 (r-3) ≥ 3(r + 5)  Remove parenthesis

-r+3≥3r+15

Step 3

-r+3≥3r+15  Subtract 3r from sides

-4r+3≥15

Step 4

-4r+3≥15  Subtract 3

-4r≥12

Step 5

-4r≥12  Divide sides by 4

Answer

r≤-3
