Solution:
we are given that
A student has some $1 and $5 bills in his wallet.
Let there x $1 bills and y number of $5 bills.
He has a total of 14 bills that are worth $34.
So we can write
Now solve these two equations together using substitution as follows
Hence there are 9 $1 bills and 5 bills are of $5.
11 pt. = 176 oz.
(Double-check if this doesn't sound correct)
8x-7 = 6x+ 5
2x = 12
X = 6, plug into equation
Y= 6(6) + 5
Y = 41
Integers are whole numbers, both positive and negative. Therefore, all of the positive and negative whole numbers between these two numbers in a set will be your answer:
