Should the solution of r+5=23 be greater than or less than 5? Why? And what does r equal? Remember to balance it out.
It should be less than, because to add 5 means that it is less than 23 because you need to add more value to get 23. r=18.
Your car has a total miles driven of 6,100. Each week, you drive 35 miles. You want to find out how many total miles you will have driven after n weeks, including the 6,100 miles. Write an equation for this, and then solve for n=5.
