The bells at kings school ring every 6 mins. at queens school the bell ring every 5 mins. at princess school the bell rings every 9mins. all three bells ring together at 8: 30am. when is the next time the bells of the three schools will ring together?

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

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.
