Answer:
Option C
Yea it dose but it still doesn't work out well
Answer:
-6 < x < -3
Step-by-step explanation:
21 < -3( x – 4) < 30
Divide all sides by -3, remembering to flip the inequalities
21/-3 > -3/-3( x – 4) > 30/-3
-7 > x-4 > -10
Add 4 to all sides
-7+4 > x-4+4 > -10+4
-3 > x > -6
Rewrite
-6 < x < -3
