Step-by-step explanation:
Look at the arrow graph below; the more the dot is on the left means the more less number, the more the dot is on the right it means the more greater number. Sorry if my explanation is confusing.
1495-400=1095
1095=15x
x=73
X: number of seats
Answer:adult=75
Students = 200
Children=75
Step-by-step explanation:
Let x= adult tickets, y=students, z=child
x+y+z =350
Since x=z
y+2z= 350 -----------1
20x +12y + 10z = 4650
Since y=z
12y +30z = 4650 --------2
Using elimination method to solve eqn 1&2
Multiply eqn 1 by 12
12y + 24z = 4200
12y +30z = 4650
Subtract equ 2 from 1
-6z =-450
z=75, x = 75
y=350 -(75+75)
y= 200 tickets
