Answer:
A
Step-by-step explanation:
We can solve this using substitution.
because x-y=2.5
x=y+2.5
Now substitute x into other equation.
2(y+2.5)^2-2y=125
2y^2+10y+12.5-2y=125
2y^2+8y-112.5=0
Now comes the ugly part
y=-4+-sqrt(16+900)
y=-4+-sqrt916
y=-4+-2sqrt229
x=-1.5+-2sqrt229
4 and 5 are two integers between 2 and 6
5. 1,000 and then 10
6. 70,000 and then 700
7. 3,000 and then 30
8. 800 and then 8
hopefully i could help ;)
