11x represents the fiction
X represents the nonfiction book
11x+x=312
12x=312
Divide both by 12
X=26
To find the fiction you have to do 11 times 26
11•26=286
To check the answer you add 286 and 26
If it adds up to 312 the answer is correct

Step-by-step explanation:
We are given the following in the question:
Let P be the number of professor and S be the student in a college.

The above situation is the situation that represents the given relationship.
Answer:
20079.05 cm^2,
Step-by-step explanation:
Surface area of the box without the lid
= 90*42 + 2(90*34) + 2(42*34) = 12756.
Now find Surface area of the half cylinder:
The diameter of the 2 half circles = 42 so the radius = 21.
The area of the lid
= 2 + 1/2 π (21)^2 + π r * 90
= 7323,052
Total = 20079.052
a rough estimate is 26 because 20+2(3)=26
3 pounds of apples are 6.36
19.75+ 2.12(3) = 26.11
