Answer:
Total tickets = 70
Total cost = $550
Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4
Assume all 70 are child's tickets
5 x 70 = 350
But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.
200 ÷ 4 = 50
So there are 50 adult's tickets.
70 - 50 = 20
And there are 20 child's tickets.

Answer:
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
Answer:
x=15
Step-by-step explanation:
subtract a 20 from each side
3x=75
divide each side by 3
x=25
remember to do each step to both sides of the equation to keep it equal
1) Find x
The equation is:
4x=64
x=64/4=16
answer: x=16º
2)Find y:
The equation is:
(2y)+(3y+5)=180
5y=180-5
5y=175
y=175/5
y=35
Answer: y =35º
Find the measure of each angle...
3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º
Answer: ∠a=46º.
4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º
Answer: ∠b=134º
5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º
Answer: ∠c=134º
6)∠d
112º+d=180º
d=180º-112º
d=68º
Answer: ∠d=68º
7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º
Answer: ∠e=48º
8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º
Answer: ∠f=132º
