Meg practice the piano for 5/12.she did homework for 3/4 of an hour. how much longer did she do homework than she practice piano

Homework = 3/4 hour = 9/12 hour

Piano = 5/12 hour

9/12 - 5/12 = 4/12 hour = 1/3 hour = 20 minutes

So she did homework 20 minutes longer than practicing piano

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

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'.
