Answer: The dog ran outside, and it played in the yard.

A compound sentence consists of two or more independent clauses, each capable of standing alone as a complete sentence, joined by a coordinating conjunction (like 'and', 'but', 'or') or a semicolon.

What is the value of x in the equation 3x+4=19?

Answer: 5

To solve the equation 3x + 4 = 19, first isolate the term with x by subtracting 4 from both sides, resulting in 3x = 15. Then, divide both sides by 3 to find the value of x. This yields x = 15 / 3, which simplifies to x = 5.
