Know the Answer?

Carlos Kirby · Answer 1

3x + 3 > or equal to 21

3x > - 3 + 21

3x>18

x> 18/3

x> or equal to = 6

3 (6) + 3 > 21

18 + 3 > 21

21> 21

So remember greater than or equal to

6 for x is equal to

12 for x is greater than

3 (12)

18 for x is greater than 21. 3 (18)

Answer is (6,12,18)

3 (2.8) = 8.4 + 3 is only 11.4 < 21
