Question

Cadets are marching in a parade. There are 5 cadets in a row. What is the rule which gives
the number of cadets, given the number of rows? (Use n for the number of rows.)​

Answer 1

Answer:

5n

Step-by-step explanation:

We know that

No. of cadets in 1 row=5

No. of cadets in 2 row=5×2=10

No. of cadets in 3 row=5×3=15

So,

No. of cadets =5×no. of rows

Now, taking no. of rows=n

Therefore,

No. of cadets=5×n=5n

Where n=no. of rows

Answer 2

Let n be the number of rows

Number of cadets in a row = 5

Total number of cadets = number of cadets in a row × number of rows

= 5n
