2x+7x=747
9x=747
x=83
83(2) = 166
83(7) = 581
So if you find the length of 2 of the sides then you find the length of the other two, so now you have all the side lengths. You add all the lengths up and then you have your perimeter.

Answer:
y = -6/7 + 410/7
(y = mx + c)
Step-by-step explanation:
72x + 84y = 4920
84y = -72x + 4920
y = -6/7 + 410/7
Answer:
The Answer is: $4.32 for a 24 ounce bag.
Step-by-step explanation:
One way to solve this is by cross multiplying after setting up a ratio:
2.88 / 16 = x / 24
16x = 2.88 * 24
x = (2.88 * 24)/16 = 69.12 / 16 = $4.32
Another way is to get the cost per ounce and multiply:
2.88 / 16 = .18 per ounce.
24 ounces * .18 = $4.32
