Alright! In order to solve this you have to work backwards. So, you know her end total is 36. And to get to that she bought 16 books. So:
36 - 16 = 20.
So, after she sold half her books she had 20. To find how many she started with you do the opposite of dividing by 2, multiplying by 2. So:
20 x 2 = 40.
She started with 40 books.

Answer:
6
Step-by-step explanation:
I am not completely sure.
3x
if x=4 then it would be 12
if x=6 then it would be 18
if x=9 then it would be 27
if x=10 then it would be 30
the side is shorter than 19 but definitely longer than 6. To me, it looks like a little more than double, more of triple and 6 times 3 is 18.
Y = 3.5(-10) + 5
y = -35 + 5
y = 30
y = 3.5(10) + 5
y = 35 + 5
y = 40
[30, 40]
