PLEASSSEEE ELXPLAIN THE ANSWER I REALLY NEED HELP ON THIS
Stephen read a 90-page book in 6 days. If he continues reading at that rate, how long will it take him to read a 300-page book?

It will take him 20 days to read a 300-page book.

Step-by-step explanation:

Given:

Stephen read a 90-page book in 6 days.

If he continues reading at that rate.

Now, to find the time it will take him to read a 300-page book.

So, we solve using unitary method:

If, Stephen read 90 pages in 6 days.

So, Stephen read 1 page in = days.

Thus, Stephen read 300 page in =

Therefore, it will take him 20 days to read a 300-page book.

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'.

no solution
