Nicholas has a collection of books. He has 115 fantasy and science fiction books. These books are 46% of his collection. How man

Anit [1.1K]

Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.

Now we have to find what is total number of books in his collection.

Let number of books in Nicholas collection = x

then number of fantasy and science fiction books = 46% of x = 0.46x

We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:

0.46x=115

now we can solve this equation to find the answer.

$x=\frac{115}{0.46}$

x= 250

Hence final answer is:

Nicholas has 250 books in his collection.

What should be done to both sides of the equation in order to solve y + 8.5 = 17.2?

Amanda [17]

Answer:

Subtract 8.5

Step-by-step explanation:

To solve the equation, y has to be isolated (only y will be on one side of the equation)

To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.

So, the correct answer is subtract 8.5
