9/15. There are 15 cards and 8 of them are odd and 1 is a 2.
Answer:44
Step-by-step explanation:
Because all angles are the same on a triangle
63/12 = 4.2
4.2 x 12 = 50.4
x = 50.4
20: 30-4 x (2+5)=2
21. 17-(8-5)= 14
22. You put (10/2)-3+1, but it isn't necessary
Explanation: to solve these equations, use PEMDAS (parentheses, exponents, multiplication, division.) these equations don't involve exponents, though, so ignore that part. If 30 is left alone, you would multiply 4x2 before doing anything else. This would mean you would have 30-8+5' which gets you to 27, an incorrect answer. However, if you put parentheses around (2+5), you add those first, meaning you would then have 30-4(2+5) = 30-4(7) = 30-28= 2.

Answer: 250 hamburgers
Step-by-step explanation: x= hamburgers
If there are 72 more cheeseburgers than hamburgers there are:
x+72
The number of cheeseburgers and hamburgers=572 so:
572= x+72+x
Then solve
572=x+72+x
572=2x+72
-72 -72

500=2x
500/2=2x/2
250=x
