There is a total of 36 books on the bookshelf. The number of hardback books is 15 more than twice the number of paperback books.

uranmaximum [27]

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:

$T = H+P$

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

$H =2P+15$

Substituting the given parameters into the formula, we have;

$36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}$

P = 7 books

For number of hardback books:

$H =2P+15\\\\H=2(7)+15\\\\H=14+15$

H = 29 books

Answer:

3rd Option

Step-by-step explanation:

Which equation is the inverse of y = 7x2 – 10?

y = StartFraction plus-or-minus StartRoot x + 10 EndRoot Over 7 EndFraction

y = plus-or-minus StartRoot StartFraction x + 10 Over 7 EndFraction EndRoot

x = plus-or-minus StartRoot StartFraction x Over 7 EndFraction + 10 EndRoot

y = StartFraction plus-or-minus StartRoot x EndRoot Over 7 EndFraction plus-or-minus StartFraction StartRoot 10 EndRoot Over 7 EndFraction
