First distribute the 6, the equation would be 9x-6x-24. combine the 9 and the 6, the final equation would 3x-24.
Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:
2.25/ 1.5 = x/1
2.25 is the 2 1/4 converted which is the amount of hours she took.
1.5 is the 1 1/2 converted which are the amount of pages she wrote total.
1 on the right side of the proportion represents 1 page.
And x are the amount of hours used to write 1 page.
And in solving that proportion it would result in 1.5 or 1hr. and 30 min.
The area would be 22 if I'm not mistaken. You would divide 69.08 by 3.14 and you would get 22.
