Answer: 13 hours
Step-by-step explanation:
The scenario that is being described can be fully made into an equation using three variables. These would be w for the number of weeks, b for the number of hours she babysat that week, and x for the total amount of hours worked. Like so...
5w + t = x
Since we are told that we need to find the total hours worked for a single week (w = 1) and that Erica babysat for 8 hours that week (b = 8), then we only need to solve for the total amount of hours worked (x)
5(1) + 8 = x
5+8 = x
13 = x
Erica worked a total of 13 hours.

M-4n=8 divide both sides by 4.
m-n=2
There are two variables, so this is the simplest form.
