They are 44 and 45.
The pages of a book are numbered from 1 to 128. How many page numbers contain the digit 6?
122 and 123How?|vif the page is double sided then it has two numbers that are added... divide 245 by 2 and you get 122.5 so one page is pg. 122 and the other is pg. 123
When a book is open to pages 68 and 69, the sum of the page numbers is 137. If you wanted to solve a problem like this algebraically, you could call the left-handed page x, and the right-handed page x+1, since you know it's one larger than the left page. Then write x + (x + 1) = 137. Subtract 1 from each side and you have x+x =136 or 2x = 136. Dividing both sides by 2, we have x = 68, so the left page is 68 and the right is 69.
There are 9 pages that use a single digit (pages 1-9), leaving 495 digits - 9 pages × 1 digit/page = 486 digits There are 90 pages that use 2 digits (pages 10-99), leaving 486 digits - 90 pages × 2 digits/page = 306 digits There are 900 pages that use 3 digits (pages 100-999); this would be 2,700 digits, so the number of pages is somewhere in the hundreds. 306 digits ÷ 3 digits/page = 102 pages in the hundreds. → total number of pages = 102 + 90 + 9 = 201 pages.
It is 1.5 pages per minute or 2/3 minutes per page.
40 & 41
The two page numbers are 64 and 65. 64 x 65 = 4160.

The solution is: Let X = left page and X+1 = right page. X + (X+1) = 89. Solve for X; X = 44 which is left page and right page is X+1 = 45.
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.
Let the two facing pages be represented by x and (x+1). Since the product of the page numbers is 1056, we have the equation x(x+1) = 1056. This simplifies to x^2 + x - 1056 = 0. By solving this quadratic equation, we find the page numbers to be 32 and 33.
The pages of a book are numbered from 1 to 128. How many page numbers contain the digit 6?
They're layouts that cover two facing pages. There are two kinds--double-page spreads, which cover any two facing pages in the book, and double-truck layouts, which cross the middle of a saddlestitched book.
The page numbers would be 166 and 167.
There are 331 such numbers.
pages 56 and 57
Books have numbers on the pages so that you can return to that spot if necessary. The number is usually on the bottom of the page. Sometimes a book will have an index that gives page numbers by the subject they contain.
