Vlad [161]
If the cost of adult ticket is x and that of children ticket is y
Then 3x +y = $38
         3x+2y =$52, solving simultaneously
we subtract the two equation,
              -y = -14 
thus; y =14 
to get x we substitute y with 14
            3x = 38-14
              3x =24
                x =8
Therefore, the cost of 1 adult ticket is $8 while the cost of children ticket is $14

A regular octagon has side lengths of 9 units. Each side of the octagon is
nirvana33 [79]

Answer:

The perimeter of the original octagon is:

  • <u>72 units. </u>

The perimeter of the new octagon is:

  • <u>288 units.</u>

Step-by-step explanation:

When it is mentioned that an octagon is regular, it means that all its sides are equal, therefore, each side of the original octagon has a length of 9 units, considering the formula of the octagon's perimeter:

  • Perimeter of an octagon = 8 * length.

By replacing you get:

  • Perimeter of the original octagon = 8 * 9 = 72 units.

For the new octagon, it is mentioned that each side increases by 27 units, therefore:

  • New length = 27 + 9 = 36 units.

Applying the formula of perimeter of an octagon with the new values we obtain:

  • <u>Perimeter of the new octagon = 8 * 36 = 288 units.</u>
