The product of 5 and n is written as 
.
Two less than this product is 
6[13-2(4+1)]
Solve what is in the bracket first.
Parenthesis first.
6[13-8-2]
6(3)
18
8z-22=3(3z+11)-z
9z-22=9z+33
-22=33
or
0=55
either way no solution
Answer:
5 min
Step-by-step explanation:
time taken=distance required to travel/speed of train
total distance train have to cover to just left the tunnel is (lenght of tunnel+length of train) =2km+250m
=2250m
speed of train is 27km/hr
multiply 5/18 to convert in m/s
i.e, (5/18)×27=7.5m/s
now time taken =2250m/(7.5m/s)
=300s
and,300s =5min
Answer: 27
