You can set up a proportion for this problem. Let the total number of books = x
The number of non-fiction books to the total number of books is
3/(7 + 3) books = 3/10
3/10 = 240/x Cross multiply
3x = 240 * 10 Combine the right
3x = 2400 Divide by 3
3x/3 = 2400/3 Divide
x = 800
Answer: 800 books in total.
Well the answer of 5+4 is nine so a double fact is not possible you have to a have a triple fact 3++3+3 equals 9 which is the sum of
6 zeros
You pretty much just multiply the 4 and the 8 and proceed by adding the quantity of zeros. So the product would be 32,000,000.

➷ y = mx + c
Substitute in values using a point on the given line
7 = m(4) + 6
-6 from both sides
1 = m4
Divide both sides by 4:
m = 1/4
The slope is 1/4
