Answer:

x=5

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

9           15

------ = ----------

2x-1        3x

Using cross products

9*3x = 15(2x-1)

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x -15

-3x = -15

Divide by -3

-3x/-3 = -15x/-3

x = 5

Elden [556K]

The monthly installments need to be paid is $10995.

To determine the number of months needed to pay off the remaining balance. We need to know the monthly installment.

<h3>What is installments?</h3>

When you get an installment loan, you get the money you borrowed or the item you bought right away.

  • You pay it off in installments, which are regularly scheduled payments that may include interest.
  • For a set number of months, or years, you generally owe the same amount on every installment.
  • When the loan is fully repaid, the account is permanently closed.
