I have way more questions than this answer them if you want pleaseee!!
aliina [53]

The right answer is Option C.

Step-by-step explanation:

Given inequality is

6(2x-1)  > 24

Solving the inequality

6*2x-1*6>24\\12x-6>24

Adding 6 on both sides

12x-6+6>24+6\\12x>30

Dividing both sides by 12

\frac{12x}{12}>\frac{30}{12}\\x>\frac{5}{2}

Therefore,

x>\frac{5}{2}

The right answer is Option C.
