First, you want to find out how many feet in a yard
3ft=1yd
so you do 21/3 to get your yard, and the answer is 7 yard
17 yard is greater than 7 yard so 17 is the answer
$20.16 because you can divide 9 by 2.5 and you’d get 3.6 and then multiply 3.6 by 5.6 and that’s what you get
6x-9-2(1-x) = x-9
6x-9-2+2x = x-9 | -x
7x -11 = -9
7x = -9+11
7x = 2
x = 2/7
