Would it be X=Y^3-2 bc I think you flip the x and y
Answer:
2y+3=5y-6. (Since all sides of rhoumbus are equal)
2y-5y=-6-3
-3y=-9
y=-9/-3
y=3
I hope it helps!!
90-40
=50(alternate angles are equal
Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
hope this helps!
