Let x tickets sold be adults, then (1024-x) were of childrens tickets, 9x+(1024-x)4 = 7680. The above equation is for total money solve it you will get x=720 hence, number of adult tickets were 720 and number of child tickets were 300 :)
Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²
Answer:
x=-4, y=8/3. (-4, 8/3).
Step-by-step explanation:
4x-9(-2/3x)=-40
4x+18/3x=-40
4x+6x=-40
10x=-40
x=-40/10
x=-4
y=-2/3(-4)
y=8/3
Answer:
fg(x)=f(10x²+5)=(10x²+5)/5+3=10x²/5+5/5+5
=2x²+1+5=2x²+6
