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
Hello! -1 - 9 is -10. F = -10. 7 - 9 is -2. G = -2.
F = -10
G = -2
d = 3
Okay, so because d and F are beside each other, we multiply both of the values. Let's plug in the values. -10 * 3 is -30. This is because one negative and one postive make a negative number. Now, we add the number. Because it is negative, we have to go into the negatives more. -30 + (-2) is -32. There. The answer is -32.
