7.2 miles per hour hope that helps if not then tell me. what is the unit or items. example:miles over hour.
Let there be a advanced tickets and s same day tickets, Then:-
a + s = 40
20a + 30s = 950............................(1)
Multiply first equation by -30
-30a - 30x = -1200 .....................(2)
Adding equations (1) and (2):-
-10a = - 250
a = -250/-10 = 25
So s = 40 - 25 = 15
Answer:- advanced tickets cost $25 and same day cost $15.
Answer:
( i ) ∠AOB = 72
( ii ) ∠BOC = 67
( iii ) ∠COD = 134
( iv ) ∠AOD = 87
Step-by-step explanation:
Sum of angles in a circle is 360,
a + b + c + x = 360
72 + 67 + 134 + x = 360
273 + x = 360
x = 360 - 273
x = 87
∠AOB = a = 72
∠BOC = b = 67
∠COD = c = 134
∠AOD = x = 87
