B: 16 and -16
two negatives = a positive
two positives make a positive :)
This would be set up as: 6/ = 25/100
so we have to cross multiply 6*100= 600 then 600 divided by 25= 24
Therefore 24 is the answer.
So there is 75 boxes of 12 right? You would figure out how much sticks you have by multiplying then you have to give them to 23 teachers. You take the total of sticks and divide among each teacher
I hope this helps :)

Let's solve for x:
100x=1000
Divide by 100
x=10
You should expect to win 10 times.
Circumference = 2 x PI x r
circumference = 3.14 x 2 x 12 inches = 75.36 inches
45/360 = 0.125
75.36 * 0.125 = 9.42 inches
