Recall that variables represent changing values. In this unit, you will work with equations that contain two different variables. What types of situations might be
modeled with equations containing two or more variables? If the value of one
variable changes, must the value of the other variable change for the equation
to remain true? How would the number of solutions for an equation with two
variables differ from the number of solutions for an equation with only one?
Explain.

answer: the answer is e

step-by-step explanation:

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

1. she sold more on day 2 because if you turn .85 into a fraction{85/100} and you give 7/9 and 85/100 the same denominator{180} you can see which one has the bigger numerator and that one will be the most sold.

2. yes it is in simplest form, because if you look at 38 and 53 's greatest common factor, you cant find one so you cant reduce it

3. no, this is not a prime factorization because the numbers are not all prime numbers, the correct prime factorization is:   2 x 5 x 2

4.   in 12 days he will run and play trumpet again

work 4 4: 123123123123

                123412341234     in 12 days he will play the trumpet and run on the same day
