Write an equation that can be used to determine the number of cups, x, of food in the container at 9:00. Write the solution to your equation.

Answer 1

x + 2 1/2 - 3/4 = 5 1/4   To find x, go backwards in the equation.
5 1/4 + 3/4 = 6 cups
6 - 2 1/2 = 3 1/2 cups
x = 3 1/2 cups

Answer 2

Answer:

X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
