What can you do to better understand an informational text?
a. read each paragraph twice
b. write out sections in your own words
c. determine the author's purpose
d. ask someone to read it aloud to you

The correct answer is C.

In order to understand an informational text we have to make sure we truly comprehend it.

The best way to make sure we know what the text is about is discovering the author's purpose. In order to have a better understanding we can ask ourselves questions like: "what is the author's opinion on this subject?"

The answer is C.

Why?

I just took the test.

- Hope this helps!

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
