Answer:
There are 30 books in the shelf.
Step-by-step explanation:
To solve this problem we can use a rule of three in such a way that 12 paperback mysteries are related to 40% of the books in the shelf in the same proportion that "x" total books are related to 100% of the books in the shelf. So we have:
12 -> 40%
x -> 100%
40*x = 12*100
40*x = 1200
x = 1200/40
x = 30 books
There are 30 books in the shelf.
Answer:
x=3
Step-by-step explanation:
4x+6=2x+12
4x+6=2x+12
4x-2x=12-6 (your letters should be on one side, numbers on the other)
2x=6
x/2=6/2
x=3
