To find the unit rate, we need to set the number of days to 1. Therefore, we will divide by 7. We also have to divide 42 by 7 to make sure the equation stays proportional. Using this knowledge, we can see that if the corn grew 42 inches in 7 days, it grows 6 inches per day.
Answer:
B
Step-by-step explanation:
The equation 
under the translation of T (p,q) will have the form 
<em>Now, using the translation T(-4,2) in the equation given, we can write:</em>
<em>
</em>
<em />
<em>Looking at the choices, </em><em>B is the right answer.</em>
2/5 * 5/7 * 1/2 <== Group first pair of fractions to make
multiplication easier
(2/5 * 5/7) * 1/2 <== Multiply fractions in parentheses, keeping in
<span> (10/35) </span> mind all rules of fraction multiplication (i.e.
(2/7) cross-multiplying, etc.)
2/7 * 1/2 <== Multiply remaining fractions
1/7
The problem simplifies to 1/7.
Hope that helped =)
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.
