The definition, theorem, or postulate that justifies the statement "If 2KL=KL+MN, then KL=MN" is the Segment Addition Postulate.
The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation:
AB + BC = AC
The definition, theorem, or postulate that justifies the statement "If 2KL=KL+MN, then KL=MN" is the Segment Addition Postulate.
The Segment Addition Postulate states that if three points A, B, and C are collinear and B is between A and C, then AB + BC = AC.
In this case, 2KL=KL+MN is equivalent to KL+KL=MN+KL, which satisfies the Segment Addition Postulate since KL is between MN and 2KL. Therefore, KL=MN

Step-by-step explanation:
Answer:
Scenario A: Survey
Scenario B: Observational Studies
Scenario C: Experiment
Scenario D: Survey
If it not the answer you can correct me
3x + y = 17
4x - y = 18
// Solve equation [1] for the variable y
// Plug this in for variable y in equation [2]
// Solve equation [2] for the variable x
// By now we know this much :
x = 5 y = -3x+17// Use the x value to solve for y
