Which of the following are steps in the process in solving application problems using the two-order system?

1. assign two variables for the unknowns.
2. make a guess for the value of the variables.
3. write two equations using the assigned variables.
4. make another guess, based on the results of the first guess. solve the pair of equations.

1 and 3

Step-by-step explanation:

For resolving an application problems using the two - order system, the following steps must be taken:

First assign two variables for the unknowns.

Second write two equations using the assigned variables.

Third solve the pair of equations.

Then, only 1 and 3 are steps in the process in solving application problems, using the two-order system

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
