Answer:
x= -3
y= -2
From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

Answer:
Radius
Step-by-step explanation:
I think we will need to use the 1mile=5280ft and the 1ft=30.48cm and the 1metre=100cm
so
3/4 mles=3/4 times 5280=3960ft
1ft=30.48cm
times both sides by 3960
3960ft=120700.8cm
1metre=100cm
1/100meter=1cm
times both sides by 120700.8
1207.008meter=120700.8cm=3/4mile
answer is 1207.008 meters
round
1207 meters
