Which is a run-on sentence? The sun was setting in the west, the clouds had become a vibrant pink.

My alarm jolted me awake, and I sprang out of bed.

Unless we distribute these flyers, people won't know about our concert.

(PICK ONE!)

Number 1

Explanation:

The sun was setting in the west, the clouds had become a vibrant pink. There is no form of transition in this sentence unlike the other 2. Sentence 2 uses "and" to separate two things that happened in the sentence and Sentence 3 uses a comma before introducing another thing in the sentence.

The first sentence doesn't use any word or comma to separate the two things within the sentence so it's a run-on sentence.

the future of her and bobby i think is her name got this book 1 year ago forgot her name but yeah

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
