Roderick Newman · Answer 1

8/18

Step-by-step explanation:

motorcycle has 2 wheels and car has 4

make a system of equations

m=motorcycle

c=cars

2m+4c=56

c=m+2

2m+4 (m+2) = 56

2m+4m+8=56

6m=48

m=8

8 motorcycles, substitute 8 for m in c=m+2 so 10 cars

18 vehicles total

8/18 is motorcycle
