Sory read 45 percent of the pages in a book over 3 days, and he read the same number of pages each day. if the book is 600 pages long, how many more pages does sory need to read to finish the book

330 pages

Step-by-step explanation:

Okay so let us look at what we actually need. It says that the book is 600 pages long and Sory read 45 percent over 3 days. This is actually all we need because it already tells us how much he read so far, which is 45%. If 45% is already done, how many percent is left?

100% - 45% = 55%

So he has 55% left of the book.

How many pages is that? We figure out how many pages is 55% of 600 pages. We just  multiply 55% in fraction form by 600 pages.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
