Answer:
x=12, y=6. (12, 6).
Step-by-step explanation:
3x-30=y
7y-6=3x
----------------
7y-6-30=y
7y-36=y
7y-y-36=0
6y-36=0
6y=0+36
6y=36
y=36/6
y=6
7(6)-6=3x
42-6=3x
36=3x
x=36/3
x=12
1/2 of the time
d=st
distance=speed times time
we want to find time
divide both sides by speed
d/s=t
d=20
s=40
20/40=t
1/2=t
this is in hours
she drove for 1/2 hour or 30 mins
