X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5
X = 2.8
It seems that you have missed few parts of the question.
I searched that question on internet and got the complete question as follows:
Which term does not belong with the other three: lines, segments, planes, and rays?
Answer:
Line, segments and rays all are 1-dimensional quantity like they move in just one direction. While plane is a 2-dimensional quantity like it has length and breadth.
In that case term "plane" doesn't belong with the other three.
Hence final answer is "plane".
Answer:
In this case study we have following groups:
1. Population: It had all the cars which passed the bicyclist. Out of which 3000 cars were taken.
2. Who: Each instance of a car passing a rider, means the drivers passing by.
That is the 3000 cars which passed the researcher on his bicycle.
3. What: The distance at which cars pass the bicycle rider. The distance the drivers stayed away from his bike.
A (-9.5, -9.5) B (5.5,-2.5) C (3.5,3.5)
First figure out what it mean
