Answer 1

Hi Natalie,

The sum of the page numbers on the facing pages of a book is 713

What are the page numbers?

Given: Sum of facing pages is 713

Find: Page Numbers

Your question tells you that you have a book open to two pages.

That means if the page number of the left side is p, then the page number of the right side would be one more that that so p + 1

You are told that the sum of these pages is 713

sum means to add so use +

is translates to =

(p) + (p+1) = 713

2p + 1 = 713

2p = 712

p = 356

So your pages are p = 356 and p+1 = 357

356, 357

Hope this helps, Let me know if you have further questions!

Answer 2

713 / 2 = 356.5

356 and 357
