Help! Order the tiles from greatest to least magnitude.

Greatest to Least Magnitude:  

Step-by-step explanation:

Each of the values has "absolute value" sign. What does absolute value do?

|a| = a

That means, no matter what number is inside the absolute value sign, whether negative or positive, the answer will always be positive.

Now, last number is mixed fraction, we will convert to decimal for simplicity of comparing.

First Number: |-4| = 4

Second Number: |-6| = 6

Third Number: |8| = 8

Fourth Number: |12.3| = 12.3

Fifth Number: |-20| = 20

Sixth Number:

3/10 = 0.3,

so 2  3/10th = 2.3

Ordering, we have:

Fifth number, fourth, third, second, first, sixth

The correct ordering will be:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
