Yes, they are equal.
The number of hardback books that are on the bookshelf is 29 books.
- Let the total number of books be T.
- Let the number of hardback books be H.
- Let the number of paperback books be P.
<u>Given the following data:</u>
- Total number of books = 36 books
To determine the number of hardback books that are on the bookshelf:
Translating the word problem into an algebraic expression, we have;
The total number of books is:

The number of hardback books is 15 more than <u>twice</u> the number of paperback books:

Substituting the given parameters into the formula, we have;

P = 7 books
For number of hardback books:

H = 29 books

Answer:
3/20, -3/10
Step-by-step explanation:
Its a quadratic equation, use the quadratic formula. (-b+-
)/2a
20x^2+3x-2=0
(-3+-
)/40
(-3+-9)/40
So you get 6/40=3/20 and -12/40=-3/10
