2. write an equation to solve the following. show all your work, including the steps for solving the equation and checking your answer. clearly state your answer. the perimeter of a rectangular photo is 72 cm. the length is twice the width. what are the length and width of the photo? (hint: the formula for perimeter is 2w + 2l = p where w is the width, l is the length, and p is the perimeter.)

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
