Step-by-step explanation:
log_6^36+log_6^216
= log_6^ (36 × 216)
= log_6^ (6² × 6³)
= log_6^ (6^5)
= 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

Step-by-step explanation:
Answer:
12 1/2 dollars
Step-by-step explanation:
add 10 9/10 and 6 3/5
you have least common multiple of the demoninators which is 10
so 6 3/5 is equal to 6 6/10
the you can add which gets you 16 15/10
simplified is 17 5/10 then you can change it to 17 1/2
then you subtract that from 30
30-17 1/2 = 12 1/2 dollars
