The trip to omaha to salt lake city interstate 80 is about 1516 kilometers. at 90 km perhour the trip would take about

16.84 hours

Step-by-step explanation:

You just divide the 1516 km by the 90 km to get how many hours it takes.

90 km   =      1 hr

1516 km           X

90 X = 1516

90        90

X= 16.84

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

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'.
