<u>Answer:</u>
<em>4,756.66 seconds or 1.321 hours</em>
<em></em>
<u>Here's how I got that:</u>
<em>- Simply use time formula and plug in what you know -</em>
<em> </em>t = distance/speed
↓
1,427,000,000,000/300000000
↓
t = <u>4,756.66</u>

Answer:
D. Vast Universe.
Step-by-step explanation:
The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.
If you used any other variable, you would have gotten a fraction.
Now that you found y, you can substitute it into the other equation to solve for x.
ANYWAYS, your answer is A
