4n+8=2(n+6)
Now isolate the n on one side of the equation:
4n+8=2n+12(distribution of the 2)
4n=2n+4(combine like terms)
2n=4(combine like variables)
N=2(isolate the n)
The answer is 2
Good luck!

Answer:
9:27
Step-by-step explanation:
So to get to 9:00, we need 3 minutes so now you have 27 minutes left of break. Then, you add 27 and you get 9:27. I hope this helped and please mark me brainliest!
1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
Calculate standard Z values for the given data:-
z = (80 - 110) / 20 = - 3/2 = -1.5
and z = (115 - 110) / 20 = 0.25
so we need Prob ( -1.5 < z < 0.25)
Using standard tables this comes to 0.5319 Answer
