  5. When solving each of the problems below, you must (i) use variables and the methods of solving as we have done in class -- you will get no credit for simply plugging in numbers to see if they work (ii) properly introduce any variables you use with either words or a diagram.$\bigskip $

    1. Suppose in a particular week the noon temperature on Tuesday was 7 degrees higher than the noon temperature on Monday. Also, the average temperature for the two days was 80$\U{b0}$. What was the temperature on Monday?$\bigskip $

    2. A student wants to create a poster. Because of the design for the border, the student wants the perimeter of the poster to be 30 inches. To contain the desired information, the area of the poster must be 56 square inches. If the poster must be taller than it is wide, find the dimensions the students must use.$\bigskip $
