Answer
A
Step-by-step explanation:
First, lets go through B-D and explain why they are correct.
B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.
C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.
D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.
A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.
Hope this helps!
Answer:
2 2/9
Step-by-step explanation:
6 1/3 - 4 1/9
1/3: 1x3 3x3= 3/9
1/9: 1x1 9x1= 1/9
3/9 - 1/9 = 2/9
6-4=2
Answer: 2 2/9
2xy + 8y - 8x - 32
2(xy + 4y - 4x - 16)
2(x + 4)(y - 4)
