The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
According to the question,
We have the following information:
Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.
The number of $5 and $1 bills are n.
a) So, we will have the following expression for the total money he has:
1*20+3*10+5n+n
20+30+5n+n
Now, adding the numbers together and the terms with the same variable together:
$(6n+50)
b) Now, when n = 5:
$(6*5+50)
$(30+50)
$80
Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.

1 1/3 hours. 3/4 plus 7/12 equals 1 1/3. Hope this helps
The answer is 10
This is because both points have the same x value, which is 2, which means the distance between them is a straight line. That means that we can simply find the distance between the y values, and -4 to 0 is 4 units, and 0 to 6 is 6 units, so 4 + 6 = 10.
I hope this helps!
