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

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
