3 is in the hundreds place, therefore 3 hundreds or 300
7×65 7×(60+5)
(7×60) (7×5)
(420)+(35)
The answer is 455
The answer should be 2(2b+3)
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.

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.
