Answer:
C
Step-by-step explanation:
3x-y=14
4x+y=21
add
7x=35
x=35/7=5
4×5+y=21
y=21-20=1
so (5,1 ) is the solution.
Answer:
The fraction of the entire mail each person address = 1/8
Step-by-step explanation:
Given that:
number of people addressing envelopes = 6
If they gave out 3/4 of an entire mailing address.
Then, the amount of mailing not addressed is:

If 6 people shared 3/4 of an entire mailing to address evenly.
Then: each person gets:


= 1/8
The fraction of the entire mail each person address = 1/8
Answer:
