Answer:
The right answer is 3a - 11 ≤ 7 ⇒ 4th answer
Explanation:
* Lets study the problem
- From the figure
# The blue line started from 6 and the point is bold that means
the inequality sign is ≤ or ≥
# The blue line started from 6 and moved to the negative numbers
that means the inequality is less than or equal
∴ a ≤ 6
* Now lets look to the answers
- There is only one answer has the sign ≤ , the last answer
* Now lets solve it to be sure
∵ 3a - 11 ≤ 7 ⇒ add 11 to the both sides
∴ 3a ≤ 18 ⇒ divide the both sides by 3
∴ a ≤ 6
* The right answer is 3a - 11 ≤ 7
