Match each situation to one of the equations.

Draggable item		Corresponding Item
2x=-12		The temperature was -12 degrees Celsius and rose to 2 degrees Celsius. What was the change in temperature?
-2x=-12		The temperature was 2 degrees Celsius and fell to -12 degrees Celsius. What was the change in temperature?
2+x=-12

Starting at noon, the temperature dropped steadily at a rate of 0.8 degrees Celsius every hour.

For each of these situations, write and solve an equation and describe what your variable represents.

How many hours did it take for the temperature to decrease by 4.4 degrees Celsius?

If the temperature after the 4.4 degree drop was -2.5 degrees Celsius, what was the temperature at noon?

Kiran mixes \frac{3}{4} cups of raisins, 1 cup peanuts, and \frac{1}{2} cups of chocolate chips to make trail mix. How much of each ingredient would he need to make 10 cups of trail mix? Explain your reasoning.
