Answer:

7

Step-by-step explanation:

Fiction books:  (1/6) of 30 books = 5 books

Non-fiction books:  (3/5) of (30) books = 18 books

The subtotal here is 5 + 18, or 23.  

23 of the books are either fiction or non fiction.

30 - 23, or 7, of the books remain (are neither fiction nor non-fiction).

A certain number was multiplied by 7. 4 was taken away from the product. Finally, that difference was then divided by 9, resulti
marin [14]

Answer:

7

Step-by-step explanation:

To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7
