Luckily for us, this problem solved the bulk of its own question!


Now, all we have to do is solve for "x", or the amount of fiction books and plug its value back into the original equation to find the value of "y", or the amount of nonfiction books.


2x = 38

x = 19

There are 19 fiction books.

x + y = 26

19 + y = 26

y = 7

There are 7 nonfiction books.

Hope this helps!

Answer:

Step-by-step explanation:

The numbers 0 and 1 are neither prime nor composite. They are too special because they represent nothingness (zero) and wholeness (one), so the idea of having factors for 0 and 1 does not make sense. ... For example, all even numbers are divisible by two, and so all even numbers greater than two are composite numbers.if a natural number is not prime, then we say that it is composite. ... Example: The value six, 6, is a composite number because it has four counting number factors: 1, 2, 3, and 6. We have 1 · 6 = 6 and 2 · 3 = 6. It turns out that mathematicians have declared that 1 is neither prime nor composite.

Yuri [45]

Answer:

x=65

Step-by-step explanation:

the sum of the angles of any triangle is equal to 180°. So, we do 180-50= 130. Then we divide 30 by two because there are two remaining angles so 130/2=65. x=65
