65.5
Step-by-step explanation:
I just took the assignment on edge. Good luck
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1

I have a great list that might help you learn some octagon facts!
1. Umbrellas are in the shape of an octagon.
2. As a symbol, octagons symbolize regeneration, infinity, rebirth, and transitions.
3. Octagons are hard to draw...You can find Octagons anywhere if you just look... just kidding only around stop signs. Lol
4. Octagons have eight angles and eight sides.
5. Did you know that you can draw an octagon with just a compass and ruler.
There ya go!
Happy to help. Let me know if you have more questions or any concerns.
