Answer:

Total number of orders = 77,520

Step-by-step explanation:

Given:

Number of students on team = 20

Number of students on the starting line =9

Find:

Total number of orders

Computation:

Total number of orders = 20! / [20 - 7]!(7!)

Total number of orders = 20! / [13]!(7!)

Total number of orders = [20 x 19 x 18 x 17 x 16 x 15 x 14] / [7 x 6 x 5 x 4 x 3 x 2 x 1]

Total number of orders = 77,520

What is the constant in the expression 5+7x?
Lilit [14]
Hey there!

When dealing with expressions, there are three terms that show up often: coefficient, variable, and constant. A variable is an unknown term commonly represented by a letter in equations (e.g. x, y, etc.) and a coefficient is a number attached to a variable (in your problem, 7 would be the coefficient of x, your variable, in 7x). That leaves your constant, which is simply a number that stays the same and doesn't contain a variable (e.g. 8, 10, 123, etc.). 

Your answer will be "5". 

Hope this helped you out! :-)
