While massaging the question into some form that can be answered,I'm assuming:-- exactly 4 of the 10 books are math books-- the other 6 are not math books-- you're asking how many different ways all 10 can be arrangedon the shelf while keeping the math books all together.If that's your question, then the answer is as follows. If that's not your question,then the following is the answer to my question but it won't help you at all :The 10 books are really only 7 units to be arranged ... 6 random books, andone unit comprised of math books that might as well be glued together becausethey can't separated. So the shelf arrangement involves lining up 7 things.The first can be any one of the seven. For each of those . . .The second one can be any one of the remaining six. For each of those . . .The third can be any one of the remaining five. For each of those . . ...etc.Total number of possible arrangements is (7 x 6 x 5 x 4 x 3 x 2) = 5,040 ways.

3x - 7 ≤ 9 "Seven less than" means that you subtract seven from the answer. "Three times a number" means that you multiply it. "At most" means that this is the greatest number that it can be, which is, in this case, 9. To solve this, you apply the principle rules of algebra to determine x. 3x ≤ 9 + 7 3x ≤ 16 x ≤ 16/3

It is time for the students to get into the books and quit relying on the internet because they can tell you fake things here on this internet and you can get it wrong because of it.

No, there was always supposed to be seven. Seven years at Hogwarts, seven books.

If the different books of the same type are considered to be the same, so that different arrangements of the same type of book are not considered to be different variations in the answer, then to find the different arrangements of books simply multiply 3 X 4 to find the answer 12. If each book must be placed as a separate entity (each book is completely different and the books must all be arranged separately) then the answer is 7! (seven factorial), or 7 x 6 x 5 x 4 x 3 x 2 x 1. The answer in this case is 5040. Examples: Answer 12: GGGAAAA AGGGAAA AAGGGAA AAAGGGA AAAAGGG Etc. Answer 5040: (Each number represents a different book. 4 are Algebra and 3 are Geometry, but all the books must be placed seperatly, so that makes no difference.) 1234567 7654321 7234561 7634512 Etc.
