On number 27 you would do as followed;
a-6 7
-------- = ----- You would turn a-6 into -6 so it would look like this
5 12
-6a
---------
5
Then you would turn it into a decimal to make it simpler (That's what I do)
So -6a / 5 becomes 1.2 then you would do the same to 7/12
7/12 = .583333333333 but then you would round it to .6 so ....
1.2a = .6
then you would divide .6 divided by 1.2 so... .6 divided by 1.2 = 0.5
0.5 = 1/2 so a = 1/2
Number 31 is basically the same thing
you turn 5k/10 into 0.5k
the you turn -12k/9 into -1.3
So... .5 divided by -1.3 = -2.6
-2.6 as a fraction is 2 6/10 as a mixed number
Hence, the correct option is "The 1990s basketball player did better than the current basketball player because his z-score is higher."

Hey there!
To start, since you already know your total without the tax, 60 dollars, now you have to find the sales tax.
Since the sales tax is 5% of the total, multiply 5% to 60. To do this, first convert 5% to a decimal by moving the decimal left two times. This would be 0.05. Now, multiply your 0.05 to 60:
0.05*60=3
Finally, add this sales tax to your total:
60+3=63
Therefore, your final total is 63 dollars.
