Solve both equations for y:
Set the expressions equal to each other:
So, for every nonzero number a the system of equations has
one solution.
So 3 pounds cost 4$ and we need to figure out how much it is to purchase 1 pound of them.
All you need to do is divide the given cost by the given amount of pounds.
4 / 3 = 1.33333333333
<h3>So 1 pound will cost 1.33$</h3>
Hope this helps!
Answer:
The length of the parallelogram is 18 meters
The width of the parallelogram is 16 meters
Step-by-step explanation:
The perimeter of a parallelogram is 68 meters
LEt x be the length of the parallelogram
Width is 2 meters less than its length
Width =x-2
Perimeter of parallelogram = 2(length + width)
Perimeter of parallelogram =
=
Add 2 on both sides
Divide by 4 on both sides
x=18
The length of the parallelogram is 18 meters
The width of the parallelogram is 18-2= 16 meters
Do you need both of the equations or just the entire solution?

Answer:
90
Step-by-step explanation:
10! = 10 × 9 × 8!
so 10!/8! = 10×9 = 90
