X=7.5 (d)
Since the 16 side is proportional to the 12 side, x is proportional to 10. 16/12 is 1.3333 so 10/1.333 is 7.5.

Answer: y = -x + 6</h3>
To get this answer, you subtract x from both sides to go from x+y = 6 to y = 6-x which rearranges to y = -x+6
Note that y = -x+6 is the same as y = -1x+6
We can compare this to y = mx+b form to see that m = -1 is the slope and b = 6 is the y intercept.
You have to get the amount of rakes sold and divide that by nine. So it would be:171 divided by 9 :)
