Answer:
Step-by-step explanation:
( 7x - 14 ) ( 4x + 19 )
28x^2 - 133x - 56x - 416
= 28x^2 - 189x - 416
Answer:
- A
Step-by-step explanation:
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.
Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
