You have 56 marbles to share with your friends. if each friend gets exactly 4 marbles, which equation could you use to solve for the number of friends, n?

4n = 56 is the equation

Step-by-step explanation:

You have 56 marbles to share with your friends.

Each friend gets exactly 4 marbles.

Let the number of friends be 'n'

The equation would be   = 4

By cross multiplication

4n = 56 will be the equation required to get the value of n

n =

n = 14

number of friends are 14.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
