x=27-9=18
Answer:
First, find 20% of the 200 books. Then, subtract that amount by the total and divide that amount by 20 to receive your answer.
Step-by-step explanation:
20 x 200
/100 = 40
Therefore, there are 40 books missing.
200-40 = 160
160/20 = 8 shelves are filled with books.
There are 10 shelves in total: 160 books are on 8 shelves and 40 books are missing for 2 shelves
16y²+12y = 4y(4y+3)
D. 4y(4y + 3)
