There are seven books on the floor. Let x be the number of books on the floor. The number of books on the shelf is 2 + 3x. From the information given, 3x + 2 = number of books on the shelf. Substitute x=7 into 3x + 2 to find the answer. So, there are 23 books on the shelf.
it depends on the shelf of course
The number of different ways to arrange six books on a shelf is calculated using the factorial of the number of books. This is represented as 6!, which equals 6 × 5 × 4 × 3 × 2 × 1. Thus, there are 720 different ways to arrange six books on a shelf.
Forty (40) percent of the books on the shelf are non-fiction books.
Stack the books on the shelf that is higher in height.
Not unless you use a single bookshelf. 29 is a prime number.
The number of ways that 15 books can be arranged on a shelf is the same as the number of permutations of 15 things taken 15 at a time. This is 15 factorial, or 15!, and is 1,307,674,368,000.
my clossal shelf is full of books and toys
Ratio of green books to brown books = 2 : 3 Green books = 18 : ? The common factor = 18/2 = 9 Number of brown books = 3×9 = 27 Brown books = 27 Green books = 18 Difference = 27 - 18 = 9 books
120. You do 5*4*3*2*1=120. you multiply the number that you are given for example how many times can books 3 be arranged on a shelf you multiply 3*2*1=6 that is your answer
The collective noun is a shelf of books.
The answer would be 7! or (7*6*5*4*3*2*1)=5040
