Answer: a child ticket costs $14.50
Step-by-step explanation:
x=children ticket
x+4.50=adult ticket
3 children and 2 adult
3x+2(x+4.50)=81.50
3x+2x+9.00=81.50
5x+9.00=81.50
5x+9.00-9.00=81.50-9.00
5x=72.50
5x/5=72.50/5
x=14.50
Answer:
C f(4)
Step-by-step explanation:
the answer is C f(4)
1/2*4=2
2+8=10
f(4)=10
3:00=(5,0)
6:00=(0,-5)
9:00=(-5,0)
12:00=(0,5)
#13 isn't too bad my friend. Just do 21-9, then divide by 4. So each ticket was $3.
15 is similar too. so he has 9 more than half. Take 9 away from 21, and you have 12. Double that, and you have the original 24.
Step-by-step explanation:
a rate of 12 m²/h = 12 × 10,000/3,600
= 33,3 cm²/min?
