Step-by-step explanation:

.3x \geq  -9\\x \geq -3

doesn't match

2.

-7x\geq 21\\x\leq -3

Does match, so this is the answer.

VMariaS [17]
You are given the information that he takes six lessons per week. First we will calculate the total lessons he could potentially take per year.

6 • 52 = 312

He could potentially take 312 lessons in one year.

Now that you know this information, you simply subtract the days he missed from that total.

312 - 5 = 307

Your final answer: Peter took 307 lessons during the year.
