Read the sentence from the passage and answer the question that follows: One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin.
What does the word "troubled" suggest about Gregor's dreams? (5 points)
They were devastating, causing him to sob.
O They pierced him, making his heart hurt.
They caused him some discomfort.
They were about his recent troubles.

The correct answer is C.

Explanation:

Answers A and B are too extreme; something which is troubling is only uncomfortable. Answer D is incorrect, because his recent (real) troubles probably did not involve him turning into a creature. Therefore, the correct answer must be C.

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

can you be a bit more specific
