Answer:
[tex]x=21 ways[/tex]
Step-by-step explanation:
From the question we are told that:
Bike space [tex]N=7[/tex]
Number of Bike [tex]n=5[/tex]
Generally the equation for This combination is mathematically given by
[tex]x=^NC_n[/tex]
[tex]x=^7C_5[/tex]
[tex]x= \frac{7!}{5!2!}[/tex]
[tex]x= 7*6/2[/tex]
[tex]x=21 ways[/tex]
