One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x
Answer:
Stephen's neighbors paid Stephen no more that $28.
Step-by-step explanation:
Given:
Stephen spent $5 of his earnings on snack.
He spent $17 in a new book.
He is left with no more than $6 left.
To describe how much Stephen's neighbors paid him.
Solution:
Let Stephen's earnings in dollars be = ![x](https://tex.z-dn.net/?f=x)
Amount left after spending on snacks in dollars = ![x-5](https://tex.z-dn.net/?f=x-5)
Amount left after spending on a new book in dollars =
= ![x-22](https://tex.z-dn.net/?f=x-22)
The amount remaining is no more than $6.
Thus, the inequality representing the situation can be given as:
![x-22\leq6](https://tex.z-dn.net/?f=x-22%5Cleq6)
Solving for ![x](https://tex.z-dn.net/?f=x)
Adding 22 both sides.
![x-22+22\leq6+22](https://tex.z-dn.net/?f=x-22%2B22%5Cleq6%2B22)
![x\leq 28](https://tex.z-dn.net/?f=x%5Cleq%2028)
Thus, Stephen's neighbors paid Stephen no more that $28.
You just change the mixed number into an improper fraction.
