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

Answer:
Step-by-step explanation:
hello :
let four consecutive whole numbers : n , n+1 , n+2 , n+3
the sum is : n + n+1 + n+2 + n+3 =4n+6
you can write 4n+6 to the form : 2(2n+3) means 2k ( k=2n+3)
so even number
Answer:
A=5
B=1
C=15
D=3

B, though you can look at the other numbers and find out a working proportion that's a multiple of 10.
Step-by-step explanation:
The rate of change for the function on the table is; 15 grapes eaten per minute.
<h3>What is the rate of change of the function described by the table?</h3>
It follows from the complete question that the table given indicates that;
- after 1min, 15 grapes had been eaten,
- after the next minute, 30 grapes had eaten,
- after the 3rd minute, 45 grapes had already been eaten.
On this note, it is conclusive that the rate of change of the function represented by the table is; 15 grapes eaten per minute.
