solve the inequality: -3(r-11)+15> 9
_
this is as far as Ive gotten.
-3r+33+15> 9
_
subtract 33, subtract 15 from each side.
Now when you divide by -3, you have to reverse the inequality sign. Your answer will be
r<something.
r= <_ 13
To solve the inequality -3(r-11)+15 > 9, you can follow these steps:
Step 1: Distribute -3 through 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 by -3. Since we divide by a negative number, we need to reverse the inequality sign:
r < -39/-3
r < 13
Therefore, the solution to the inequality is r < 13.
