Let

x-------> the number of fiction books

y-------> the number of nonfiction books.

we know that

x+y=26 -----> equation 1

x=y+12

x-y=12 -----> equation 2

Add equation 1 and equation 2

x+y=26\\x-y=12\\ ------\\ 2x=38\\ x=38/2\\x=19\ fiction\ books

<u>find the value of y</u>

x+y=26

19+y=26

y=26-19=7\ nonfiction\ books

therefore

<u>the answer is</u>

Part a)  the number of fiction books is 19\ fiction\ books

Part b)  the number of nonfiction books is 7\ nonfiction\ books

Calculate the area of QRS
Eduardwww [97]

Answer:

  153 cm²

Step-by-step explanation:

The area is given by the formula ...

  A = (1/2)bh

where b is the base length, and h is the height measured perpendicular to the base.

The diagram shows b = QR = 18 cm, and h = 17 cm. So, the area is ...

  A = (1/2)(18 cm)(17 cm)

  A = 153 cm²

What is the solution to the open sentence 18 = c + 6?
sveticcg [70]
This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.

Answer: c = 12 so 18 = 12 + 6 is true.
