Answer:

The adult tickets cost $9 each. The child tickets cost $5 each.

X = $9 and Y = $5

Step-by-step explanation:

$9 x 6 = $54

$5 x 2 = $10

Add them and you get $64.

For the first one, do the same.

$9 x 3 = $27

$5 x 4 = $20

Add them and you get $47

If four tires can be changed in 3/4 of an hour gow long would it take to change 19 cars​
kobusy [5.1K]

Answer:

14.25 hours

Step-by-step explanation:

Four tires = 3/4 of an hour

=> 1 car = 3/4 of an hour

=> 19 cars = ?

=> If 1 = 3/4

=> 19 = 3/4 x 19

=> 3/4 x 19

=> 57/4

=> 14.25 hours

So, it would take 14.25 hours for 19 car's tires to be changed.
