x=8 is the answer fellow user
If the gourmet shopkeeper mix 15 pounds of coffee beans which costs 3.0$ per pound with 10 pounds of coffee beans costing 4.25$ per pound.
The mixture of 25 pounds will cost 3.5$ per pound.
It can be found using
3*x + 4.25*(25 -x) = 25*3.50
The correct answer would be a Right triangle
2(4x - 9) =
2 * 4x - 2 * 9 =
8x - 18
Hope this helps!!
