Answer:

x=8 , w=106.

Step-by-step explanation:

To find this answer, it is quite simple. This is because you use to cross multiply rule in order to solve the problem so you multiply

100*6,  75*x and you get 600=75x. Then you solve the equation like normal. Same thing for the second equation 90*72 and 80*w you will get 6480=80w. And then solve the equation from there. I hope this helps :)))

Answer:

Jordan

Step-by-step explanation:

Because each person is in debt the one with the least amount of dept will pay less. Think of it like this:

You owe the bank 85 dollars so your account balance is -85 since you owe money

if you were to owe 100 dollars then you owe more money.

Therefore owing 85 dollars is the least amount of money owed in this case

Let x be the amount of weeks.

60 + 7x = 120
60 - 60 + 7x = 120 - 60
7/7x = 60/7
x = 8.571428571
