Two of your friends go bowling. One friend rents a pair of bowling shoes for $3 and bowls 3 games. The other friend brings his o
Nesterboy [21]

Answer: The cost of each game is $2.50

Step-by-step explanation:

Let's find the equations for each friend:

Friend 1:

Pays $3 for the shoes, and plays 3 games, then if X is the cost of each game, Friend 1 pays a total of:

$3 + 3*X

Friend 2:

This friend buys a soda for $0.50, and he plays 4 games, remember that the cost of each game was X. then this friend pays:

$0.50 + 4*X

And we know that both friends pay the exact same amount, then we can write:

$3 + 3*X = $0.50 + 4*X

And solve this for X.

We need to isolate X, then we can move all the terms with X to the right, and all the terms without X to the left:

$3 - $0.50 = 4*X - 3*X

$2.50 = (4 - 3)*X = X

This means the cost of each game is $2.50

Answer:

1120°

Step-by-step explanation:

Use the sum of interior angles formula:

180(n-2)

Where n is the number of sides.

In a nonagon, there are 9 sides, substitute 9 for n:

180(9-2)\\180(7)\\1260

Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:

\frac{1260}{9} =140

Subtract 140 from 1260:

1260-140=1120
