Answer:

<em>The polygon has 15 sides</em>

Step-by-step explanation:

<u>Angles in a Regular Polygon</u>

A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that in a regular polygon, each angle measures

\displaystyle \frac{180(n-2)}{n}

The regular polygon's interior angle is 156°, thus

\displaystyle \frac{180(n-2)}{n}=156

Multiply by n:

180(n-2)=156n

Operate:

180n-360=156n

Reducing:

24n=360

Solving:

n=15

The polygon has 15 sides

The cafe sells Beetle Juice and Potion Punch. A cup of Beetle Juice costs $2.50 and a cup of Potion Punch costs $3. Owen ordered
nexus9112 [7]

Answer:

2  Beetle juices and 3 Potion Punch

Step-by-step explanation:

j = Beetle Juice       cost $2.50

p = Potion Punch      Cost $3

         j + p = 5                      <em>Multiply by -3</em>              -3j  - 3p = -15

$2.50j + $3p = $14           <em>Do not change      </em>+ <em>  </em><u><em> </em></u><u>2.50j  -3p = 14      </u>

                                                                                 - .50j      = -1

                                                                                          j = 2   Beetle Juice

   Substitute into the fist equation and solve for y       j + p = 5

                                                                                         2 + p = 5

                                                                                              p = 3   Potion Punch
