gavmur [86]

Answer:

  • 321 adult tickets
  • 227 child tickets

Step-by-step explanation:

This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...

  6.50x +3.50(548-x) = 2881

  3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms

  3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918

  x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3

  548-x = 548 -321 = 227 . . . . . .number of child tickets

321 adult tickets and 227 child tickets were sold.

Please help me get the right answer?!
Aleksandr-060686 [28]
The answer is A, \frac{1}{81}. This is because when plugging in -2 for x, the expression will look like this: 9^{-2}. To make the exponent positive, you have to flip it into a fraction. Then it will be \frac{1}{9^2}. Lastly, you simplify the denominator into 81.

Jonathan weighs thirty pounds more than three times his son Aidan's weight.Their combined weight is 210 pounds.Write an equation
aalyn [17]
The equation should be
j = 30 + 3a
j + a = 210

Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45

j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165

Aiden's weight is 45 pounds, Jonathan's weight is 165 pounds
