Answer:
Step-by-step explanation-3:
Left at 3 p.m
traveled 1 hr 30 min......now its 4:30 p.m.
stopped for 15 min....now its 4:45 p.m.
continued for 2 hrs 10 min....now its 6:55 p.m
so the train arrived at 6:55 p.m.
- 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x / = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;
The solution of the system is ( 14/3 ; 10/3 )
