It can go up to four dimensional.
1x+2x = 18
3x=18
x=6
there are 6 pieces of yellow chalk
start with elimination. 8 x 8 is only 64 so C and D dont make sense. The are of the circle is pi(r)². so the radius is 4 squared then multiply by pi and devide by 5 to get the 5 equal parts. So B 10.
8 goes with 3/5: 10 goes with n (n being the number of cups)

Use cross products and we get 8n = 6
Now divide by 8
<u>8n</u> = <u>6
</u><u />8 8
n= 6/8 or 3/4 of a cup of flour.
