Will mark jamie has 12 quarts and 3 cups of ice cream. she serves some of the ice cream. jamie has 3 quarts and 2 cups of ice cream left. choose all of the equations that can be used to find the amount of ice cream that jamie served. answer choices 3quarts,2cups−12quarts,3cups=? 12quarts,3cups−3quarts,2cups=? 3quarts,2cups+? =12quarts,3cups 12quarts,3cups+3quarts,2cups=?

I think the answer would be 3quarts,2 cups+? = 12 quarts, 3 cups (C)

12quarts 3cups-3quarts 2cups
And
3quarts 2cups+?=12quarts 3cups

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
