3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
I would say B because it only makes since, colleges are looking for whats better in students and you will also work in groups also. So i would go with B :)
The solution should be x=5
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
Put all numbers in order from least to greatest
median is the middle number
so
5,9,10,11,12,14
median = ( 10+11)/2 = 10.5
answer
C. 10.5
