------------------------------------------
Define adult and student tickets
------------------------------------------
Let the number of adult tickets be x
Adult tickets = x
Student tickets = x + 69
------------------------------------------
Form equation and solve for x
------------------------------------------
x + x + 69 = 569
2x + 69 = 569 ← Combine like terms
2x = 569 - 69 ← Subtract 69 from both sides
2x = 500
x = 250 ← Divide by 2 to find x
------------------------------------------------------------------------------------
Find the number of adult tickets and student tickets
------------------------------------------------------------------------------------
Adult tickets = x = 250
Student tickets = x + 69 = 319
------------------------------------------------------------------------------------
Answer: Adult tickets = 250 ; Student tickets = 319
------------------------------------------------------------------------------------
Answer:
35%
Step-by-step explanation:
Answer:
the pattern step number of second step is added to number of balls used of first step to get number of balls used of second step
that is
1 + 2 ( number of balls added to pattern step number) = 3 (number of balls used)
in the same way
6 + 4 = 10 ( first blank )
5 + 10= 15 ( second blank)
15 + 7 = 22 ( third blank )
22 + 8 = 30 ( fourth blank)
