Answer:
30
Step-by-step explanation:
PT = TQ
PT = 7x + 2
TQ = 9x - 6
7x + 2 = 9x - 6
9x - 6 = 7x + 2
9x - 7x = 2 + 6
2x = 8
x = 8 / 2
x = 4
Substitute x = 4 in PT,
PT = 7x + 2
= 7 ( 4 ) + 2
= 28 + 2
PT = 30

The number of books that can be shelved is 45. So then we know that the amount that need to be shelved <em>can</em> be 45, if the bookshelf had 0 books on it. This means that it can have the equal part of the inequality sign.
However, the amount of book that need to be shelved cannot <em>exceed</em> 45, so b must be less than 45.
Therefore, the answer must be D) b ≤ 45.
