The answer to this question is the second choice, SOMETIMES, because there are those systems of linear equations that the lines are parallel and do not intersect therefore has no solution. There are also other systems representing the same line and has therefore infinite number of solutions.
<h3>Answer:</h3><h3>:::::::::</h3><h3>Explanation:</h3>
It would be 7 because if you multiple 6 you get 1
For no. 62 the answer is A.
Answer: 14.32 degrees
The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers
A full perimeter </span>of the circle, which is 25.14km, has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°
