Let x be the number of pages of advertisements. 
Write a proportion from the table:
 of a page of advertisment - 5 pages in a magazine
 of a page of advertisment - 5 pages in a magazine
x pages of advertisment - 98 pages in a magazine,
then

Find x:

Answer: 13 whole pages and  of 14th page are advertisments, so 14 pages contain advertisments.

Answer: 3
Step-by-step explanation:
You can answer this question by using the equation 
(8+x)(7+x)=110
The x represents the width, as we do not know the area. If you simplify the equation, it becomes 56+15x+x2=110.
If you move all the terms to the left side, and rearrange it, it can become x^2+15x-54=0
This can be simplified into (x-3)(x+18)=0
This equation makes it so that x is either 3 or -18. It is not possible for a width to be -18, so the width must be 3.
