b < 5
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

Answer:
0.0000302
Step-by-step explanation:
When 10 is to the power of a negative number, "move" the decimal dot left.
10⁻⁵ means to "move" the decimal 5 times to the left.
1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02).
0000003 . 02
2. Count 5 place values over.
00←0←0←0←0←3 . 02
3. Put the decimal behind the digit.
00 . 0000302
4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal.
0.0000302 <= Final answer
