Answer:
Supplementary, 39+5x=180, x=28.2
Step-by-step explanation:
So we know that a straight line is 180 degrees, therefore 52+(5x-13) must equal 180. This is a supplementary relationship. That's our equation, now we just have to solve.
52+5x-13=180
We can straight away combine numbers, giving us
39+5x=180
Now we subtract 39 from both sides, giving us
5x=141.
Now we will answer.
141/5=28.2=x
I'm not sure if this is right, but this is my answer :)

Answer: 4
Explanation:
You can write an algebraic expression to represent the sequence with the books in this way:
- yesterday she got five books: 5
- today returned three books: - 3
- how many books did Gia have to begin: n
- At the end she has six books, which means that you can set an equality:
n + 5 - 3 = 6
Now you follow these steps to clear the unknown:
- do the operations in the left side: n + 2 = 6
- use subtraction property of equality: n = 6 - 2
- do the operations: n = 4
And that is the number of books whith which Gina started: 4
