Answer:
480
Step-by-step explanation:
Important Information:
A Book Has 12 Chapters.
The Mean length of the chapters is 40 pages.
Question to Answer:
How many total pages are there in the 12 chapters?
Explanation/Solution:
Let's assume that the total number of pages in the book is "x" pages.
To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.
=40
Multiply both sides by 12...
x = 480
Hence, The total number of pages in the 12 chapters is 480.
Answer:
2.90m
Step-by-step explanation:
I hope this is the answer.
The answer is 12 it’s basically 17-5
15x + 11x + 8x+5 = 180
34x + 5 = 180
34x = 180-5
34x = 175
x = 5.147
by substitution each value by of x by 5
75 + 55 + 45 = 175
If you are trying to simplify it, I think it would be -22<36. Im not sure because I haven't learned this that much in school yet. I do know that if you are confused on how to do it, you can use...

This is the order that you do to solve the problem, For example,
P stands for Parentheses
E stands for Exponents
M stands for Multiplication
D stands for Division
A stands for Addition
S stands for Subtraction
This is the order of how you solve the problem. If one of the things aren't in the particular problem, then skip that certain step. For example if Addition wasn't in the problem, then you would skip the A. I hope this helps!
