In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
= 256/10
= 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
= 54.4 pages
So Katie has 54.4 pages left to read.
You have a lot of questions here, try breaking them up into multiple posts and you may get more responses.
I will help with some.
<span>(x+3)=0
The solution is just -3.
-----------------------------------------------------------------
3m(m-4)=0
The two solutions are 0 and 4.
-----------------------------------------------------------------
(r-3)(r+2)=0
The two solutions are and 3 and -2.

I hope this gets you started in the right direction.
I'm pretty sure it's 1/10 because it is one out of ten instead of one out of 12 ya feel
Linear functions parabola mostly things in algebra
6.7 x -2.3
You would multiply this just like any other multiplication question.
There is some work of course, but I'm not going to write it out here...
You are going to end up with -15.41, which is already rounded to the nearest hundredth.
Hope this helped :)
