Answer:
11
Step-by-step explanation:
71-60=11
C=number of cars
t=number of trucks
c+t=127=total
if there are 4 more than (+4) 2wice the number of trucks (2 times t or 2t) than are cars (= c) find c and t
4+2t=c and c+t=127
subsitute 4+2t for c
4+2t+t=127
4+3t=127
subtract 4
3t=123
divide 3
t=41
subsitute
t+c=127
41+c=127
subtract 41
c=86
86 cars
41 truckes
B "it's" means (it is) and that would not make sense if it fell on it is side .
