Answer:
Jessica pays $10 more than Nancy for membership fee.
Step-by-step explanation:
Jessica pays a membership fee of $40, and she pays $5 for every video game she rents.
So, we can write this as :
'x' is the number of games rented.
And equation for Nancy is :
If we look at the equations we can find that, the numbers 40 and 30 are constant i.e the membership fee.
And 5x and 4x are variable terms that change with the number of games rented.
So, Nancy's membership fee is $30. This is dollars less than Jessica.
Therefore, Jessica pays $10 more than Nancy for membership fee.

In order to divide integers, the first thing to check is the sign:
- When dividing two positive integers, the result will be a positive integer.
- When dividing two negative integers, the result will be a positive integer.
- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.
Then, after checking the sign, we need to calculate the value of the division.
Some examples of divisions are:
In the first division, the result is 3, because we have that 8 * 3 is equal 24.
Also, both numbers are positive, so the result is also a positive number.
In the second division, the result is -3, because 5 * (-3) is equal -15.
The result is negative, because the two numbers have different signs.
In the third division, the result is 10, because -10 * 10 is equal -100.
The result is positive, because both numbers are negative.
