A messenger is sent to a town and advances daily by twenty miles. In how many days will another messenger, sent five days later and advancing daily by thirty miles, overtake him?
STEP BY STEP: You will do the following. Take the difference between twenty and thirty, namely ten, as the principal. Next, multiply five by twenty and divide the product by the principal; this will give ten, and so many days did the second messenger walk. The first has been on his way that many days plus five, which is fifteen, when the second messenger met him.
answer: there are x+184 pages in olivia's book.
let the total number of pages in the book which olive has already read be x.
then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read
therefore, the total number of pages in olivia's book=
hence, there are x+184 pages in olivia's book.
-12 > a
-11 > 1 + a
subtract 1 from each side
-11 -1> 1 -1+ a
-12 > a
