dropped $3 means "-3", increased $6 means "+6"
the price dropped twice so 2(-3) and increased once by 6
so, 2(-3) + 6 = 0
the change in price is $0
I believe x=10.25 because of the pythagorean theorem.
5.14- 3.89 = 1.25 1.25/ 0.25 =5 m=5 I think, you might want to check it :)
2x + 5 = 27
2x + 5 (-5) = 27 (-5)
2x = 22
2x/2 = 22/2
x = 11
hope this helps
