Child admission is 5.50 and adult admission is 8.80, twice as many adult tickets as child tickets were sold, for a total of 669.
Vlad1618 [11]

Answer:

The answer to your question is: 29 tickets for children and 58 tickets for men.

Step-by-step explanation:

Child = c = $ 5.50

Adult = a = $8.80

Equation

                                  a = 2c

                           5.5c + 8.8a = 669.9

                           5.5c + 8.8(2c) = 669.9

                           5.5c + 17.6c = 669.9

                           23.1c = 669.9

                           c = 669.9 / 23.1

                          c = 29

                           a = 2(29)

                          a = 58

PLEASE HELP!! WORTH 30 POINTS!! WILL GIVE BRAINLIEST TOO!
RoseWind [281]

Answer:

x = 15/11

Step-by-step explanation:

(segment piece) x (segment piece) =  (segment piece) x (segment piece)

(x+3) *x = 2x*(6x-6)

Divide each side by x

x+3 = 2(6x-6)

Distribute

x+3 = 12x-12

Subtract x from each side

x+3-x = 12x-x-12

3  = 11x-12

Add 12 to each side

3+12 = 11x-12+12

15 = 11x

Divide each side by 11

15/11 =x
