Step-by-step explanation:
Answer:
x= 1/2
y=3
Step-by-step explanation:
it is easier to subtract both equation and obtain a new one
1) 6x+0.4y=4.2
2) -4x+0.4y=-0.8
---------------------------------
1) -2)= 10x+0=5 leading to x=1/2
Now just eval x=1/2 in any of the original equations, for instances
1) 6*(1/2) +0.4*y=4.2, which leads to y=3
First make an equation
444=x+y
3x=y
(X=adult tickets, y=student tickets)
So then fill in y from the second equation into the first
So
444=x+3x
So x=444/4
So x=111
Y=444-111=333
Lets verify
3*111=333
So answer 111 tickets
Coordinates of Midpoint, knowing A(x₁, y₁) and B(x₂, y₂) is
x(of midpoint) = (x₁+x₂)÷2
y(of midpoint) = (y₁+y₂)÷2
Let A(4, -2) be one end point and B(x₂, y₂) , the other end point. Moreover the coordinate of the midpoint are given= M(1/2, 0)
1) x(of midpoint) = (x₁+x₂)÷2 = (4+x₂)÷2 , but x(of midpoint) = 1/2
Then 1/2 = (4+x₂)÷2 and x₂ = -3
2) y(of midpoint) = (y₁+y₂)÷2 = (-2+y₂)÷2 , but y(of midpoint) = 0
Then 0 = (-2+y₂)÷2 and y₂ = 2
Hence the pair of the other end is B(-3,2)
