To change the negative to a positive, just put the same number as into a fraction under 1 but without the negative sign:
11^-4 would become 1 / 11^4
8x = 13
13 divided by 8
that would be 1.625
He eats 2 pieces because 1/3 of 6 would be 2 leaving 4 pieces remaining.
A)
Kim's age=k
Sister's age=s
k=2s
k+s=36
b)
k=2s
k+s=36
k=36-s
2s=36-s
3s=36
s=12
12*2=24
Kim is 24 and her sister is 12
Hope this helps :)
