20 kilograms = 20000 grams
Formula
Number of books = mass of bookcase / mass of 1 book
Givens
number of books = ??
mass of bookcase = 20000 grams
mass of one book = 500 grams
Solution
number of books = 20000 / 500
number of books = 40
Answer: 40 books = mass of bookcase
Subtract 6 from both sides leaving you with -2x=4 now divide -2 from both sides leaving you with x=-2
15= 3*5
14= 2*7
LCM(15,14)= 2*3*5*7= 210
15 and 14 go into 210 evenly~
