Is helper really right?
i hate to admit it but anonnymous was right, 2 was d and 7 was a. I got 6/8 so far. But it makes me look less sus so ¯\_(ツ)_/¯
Here are the answers for number 9 and 10:
1. x = .1515....
2. 100x=15.15.....
3. 100-0.1515... equals 99(do not include the non-terminating numbers, just simplify it to 99)
4. 99x=15(rounded to nearest number)
5. x=15/99=5/33
6. Check it with calculator by dividing 5 by 33
Please put this in your own words :)

#2 ok
#3 Nope. 9 is a perfect square.
#4 Nope. Suppose x = 1/6. You have 1x/2x
#5 ok
#6 ok
#7 ok
#8 Nope. A has too many -7's
#9 What's the difficulty? Just use the values given:
2s³-4r² if r=1 and s=5
2*5³-4*1²
2*125-4*1
250-4
