Answer: x = 10 y=20
Step-by-step explanation:
You can answer this question by plugging in each equation:
2x=y, x+y=30. Let us plug y as 2x in the second equation x+y=30
x+2x= 30
3x= 30
x=10
After we found x we can then find y by plugging the 10 for x.
2(10) = y
y =20
or you could plug in the other equation
10+y=30
subtract 10 from 30 and we get 20
to double check we can plug in both numbers
2(10) = 20 which is correct
and 10 + 20 = 30 which is correct

Answer: The average distance the ambulance travels to reach an emergency situation is 6.64 miles.
Step-by-step explanation:
Hi, to answer this question we have to apply the speed formula:
Speed rate = distance / time
Replacing with the values given:
0.83 miles per minute = d / 8 minutes
Solving for d (distance)
0.83 mpm x 8 m =d
d =6.64 miles
The average distance the ambulance travels to reach an emergency situation is 6.64 miles.
