Nine kids and three adults are going to the circus. kid's tickets are on sale for only half the price of adult adult ticket. the total cost is $117. how much is one kids ticket? how much is one adult ticket?

the cost of one kids ticket is $7.8

the cost of one adult ticket is $15.6

Step-by-step explanation:

Let x represent the cost of one kids ticket.

Let y represent the cost of one adult ticket.

Nine kids and three adults are going to the circus. The total cost of the tickets is $117. It means that

9x + 3y = 117 - - - - - - - - - - - - 1

Kid's tickets are on sale for only half the price of adult adult ticket. This means that

x = y/2

y = 2x

Substituting y = 2x into equation 1, it becomes,

9x + 3 × 2x = 117

9x + 6x = 117

15x = 117

x = 117/15 = 7.8

y = 2x = 2 × 7.8

y = 15.6

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
