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.
The answer is 2.5 cookies also known as 2 and 1/2 Because 12 can go into 30, twice , which gives us 24 and 30-24= 6 so we put a decimal point to the right of 2 and we put a 0 and bring the zero down to make 60. 12 goes into 60, 5 times so the answer is 2 1/2 or 2.5
Answer:
21 grapes.
Step-by-step explanation:
We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.
First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.


Now, we will find half of 6 to find number of grapes eaten by Lucy.
