Solve the inequality : -3(r-11)+15≥9
whats 1+1
woww..
-3r+33+15>=9
subtract33+15 from each side.
-3r>=9-33-15
divide by -3
r<-3+11+5
To solve the inequality -3(r-11)+15≥9, follow these steps:
Step 1: Distribute -3 to the terms inside the parentheses:
-3r + 33 + 15 ≥ 9
Step 2: Combine like terms:
-3r + 48 ≥ 9
Step 3: Subtract 48 from both sides to isolate the variable:
-3r ≥ 9 - 48
-3r ≥ -39
Step 4: Divide both sides of the inequality by -3, remembering to flip the inequality sign since we are dividing by a negative number:
r ≤ -39 / -3
r ≤ 13
So the solution to the inequality is r ≤ 13.
