Let us assume the number of text books sold by <span>keller publishing = x
Then
Then </span>number of text books sold by <span>Scholastic books = 4x
The total number of text books sold = 7775
Then
x + 4x = 7775
5x = 7775
x = 1555
Then
The nu</span>mber of text books sold by Scholastic books = 4x
= 4 * 1555
= 6220
I hope the procedure is clear enough for you to understand.
Answer:

7/8 + 1/8 = 1
Answer: EB is bisected by DF
A is the midpoint DF
EB is a segment bisector
FA=1/2FC.
Step-by-step explanation:
Let the youngest sister be n years
Lana will be 2n years, as her youngest sister is half her age
The age of the twins separately will be 2n-2 as they are 2 years younger than Lana
So, the equation looks like this:
n + 2n + 2(2n-2) = 45
Now solve for n:
3n + 4n - 4 = 45
7n - 4 = 45
7n = 49
n = 7
So the youngest sister is 7, Lana is 14 and the twins are 12. 14 + 12 + 12 + 7 =45
