Acarpenter uses 65 shelves to make 13 bookcases. she uses the same number of shelves for each bookcase. are 32 shelves enough to build 6 more bookcases.

Hello There!

First work out the number of shelves per bookcase:
65/13 = 5
It is 5 shelves per bookcase.
6 x 5 = 30.
Therefore 32 shelves are enough to make 6 bookcases.

Hope This Helps You!
Good Luck :)

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
