Move the 6c over to the 7c side
1c - 17 = -15
Then move the -17 over to the -15 side
C=2
First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
5:3:2 = 40 isn't true... It means that 5x = 40 and we need to figure out 2x.
So if 5x = 40, then x = 8
Meaning 2x = 16.
Causing the smallest share to be 16 apples.
70%=70/100=7/10
what you do is shade 7 of the squares and say that is 21
now each square is worth the same
so 21/7=3
each square is worth 3
10 squares
3 times 10 is 30
the number is 30
