At 9:00, Paula has x cups of food in a container for her dog. Paula pours a 2 1/2 cup box of food into the container. Then she r
emoves 3/4 cup of food to feed her dog. Now there are 5 1/4 cups of food in the container. write an equation that can be used to determine the number of cups, x, of food in the container at 9:00?
Which equation can be used to determine the number of cups of food, x, in the container at 9:00?
A.5 1/4 = x + 212 + 34
B.5 1/4 = x − 212 + 34
C.5 1/4 = x + 212 − 34
D.5 1/4 = x − 212 −34
c is 5 1/4 = x + 2 1/2 − 3/4 [ but if it is actually 212 and 34, then none of them are right. i'm just putting the division sign where i thought it should be coming off from the problem. ]
the reason why i said c is because on how it adds 2 and 1/2 cups <u>INTO</u> the container, meaning that there will be x + 2 1/2 amount of food in the container. then, <u>REMOVING</u> 3/4 cups out of the container would mean that we have to subtract it. so −3/4.
