Tickets to the local carnival cost $5.50 for adults and $3.00 for children under the age of 12. a group of 8 people bought tickets to the carnival for $36.50. write a system of equations to represent this scenario. how many adult tickets were sold?

The number of adult tickets sold was 5

Step-by-step explanation:

Let

x ----> the number of adult tickets

y ----> the number of child tickets

we know that

isolate the variable y

----> equation A

----> equation B

Solve the system by substitution

substitute equation A in equation B

solve for x

apply distributive property left side

combine like terms

subtract 24 both sides

Divide by 2.50 both sides

therefore

The number of adult tickets sold was 5

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
