Solve real-world and mathematical problems involving the four operations with rational numbers and explain the meaning in the context of the answer. (BTW you have to show an example of real world and mathematical problems by using the operation, Multiplication, Division, Subtraction, and Addition. But with rational numbers.)

See Below

Step-by-step explanation:

To Clarify a rational number is just a number that can be made into a mixed fraction. Or another way of doing this would be to say a number like 1.50. So currency is a form of rational numbers.

EX: You decided to go to college but as a broke college student you couldn't pay for college (because it is expensive) so you decide to take out a student loan. For simplicity's sake let's say that you only need a $15,236.75 loan to add to the money you had saved up for college. However, the loan agency adds a 0.05 per month interest rate as soon as your 4 years of college are over. Knowing that interest adds up fast you decide to try to pay off as much loan debt as you can while still in college with your part-time job. You end up paying off $746.98 leaving you with only $14,489.77 left of the loan. The first month out of college you wind up with only $15,214.26 of college debt. Before the next month however you marry your college sweetheart and as a couple, you take on each other's debts making your grand sum for college debts $32,416.51. After five blissful years of marriage you wind up getting a divorce but because finances have been jumbled (real-world ish) you decide just to divide the $12,758.36 debt from college evenly between the two of you.

i think the correct option is the second option.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
