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.

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below.the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
