The ballpark made a total of $15,000 from ticket sales at wednesday's game. the ballpark charges $20 for each adult ticket and $10 for each child's ticket. they sold 3 times as many children's tickets as adult tickets. write a system of equations that can be used to determine the number of adult and child tickets sold.

50x=15000, and  x>0

Step-by-step explanation:

Let the number of adult tickets be x .

then the number of children's tickets =3x

Since the ballpark charges $20 for each adult ticket and $10 for each child's ticket.

Therefore total sales on Wednesday=20x+10(3x)

=20x+30x=50x

Since the ballpark made a total of $15,000 from ticket sales at Wednesday's game.

⇒The required equation must be 50x=15000, and  x>0

is it 35

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
