Answer:
6%
Step-by-step explanation:
57 divided by 80 = 0.5875
.5875 rounded to the nearest tenth is 6%
X+2y=23
X=-2y +23
Plug this in for x in the second equation
5(-2y + 23) + 10y = 55
-10y + 115 + 10y = 55
The -10y + 10y cancel out, so there is no solution
Hope this helps!
Add numbers with common factors (the 5y and the 16y), subtract 17 from both sides
