A. Because if you use distribution you get those numbers
If there's 60 minutes in a hour. You do 20*60. Because there's 20 cars for ever minute and there's 60 minutes. So it would be 1200 cars in a hour
let h= history books
science books = s
h=2s there are 2 times as many history as science so to get them equal we double the science
h+s=81 there are 81 total history and science books
2s+s=81 substitute 2s for h in the above equation
3s = 81 combine like terms
s = 27
There are 27 science books
h=2s
h=2(27)
h=54
there are 54 history books
