total number of pages = 550 pages
total amount of time to read the full book = 10 hours
======================================================
Work Shown:
1 hour = 55 pages
4 hours = 220 pages ... multiply both sides by 4
After 4 hours, he had read 220 pages. Since he has 330 still left to read, this brings the total to 220+330 = 550 pages overall
550/55 = 10 hours is the total amount of time needed to read the entire book at a rate of 55 pages per hour. This is assuming the rate is kept constant.
While 10 hours is a lot, it's somewhat plausible to get the full book read in one continuous session. Though he is better off taking (short) breaks every now and then.

Answer:
3
Step-by-step explanation:
The function is undefined when its denominator is zero. The value of x that makes the function undefined is the solution to
10x -30 = 0
x - 3 = 0 . . . . . divide by 10
x = 3 . . . . . . . . add 3
The value of x that is not in the domain of the function is x=3. The function is not defined for that value of x.
