Answer:
Rotation of 180 degrees, either direction
Dilation, making it smaller by some factor(we aren't given measurements so we cannot be exact)
Then move the figure to the right and then move the figure up
Step-by-step explanation:
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
