Answer:
54
Step-by-step explanation:
63 x 2 = 126
180 - 126 = 54
Answer with Step-by-step explanation:
We are given that



Compare with slope-intercept form

Where m=Slope of line
b=y-intercept
a.We get slope=m=1
b.b=81
c) To find the x- intercept
Substitute y=0


x-intercept at x=-81
Senior tickets (x)
Child tickets (y)
First day: 3x + 5y = 70
second day: 12x + 12y = 216
Solve the system of equations (use elimination)
Multiply first equation by -4 -4(3x + 5y = 70), which makes it
-12x - 20y = -280
(+)12x + 12y = 216 add to second equation
-8y = -64
divide by -8. y = 8
Plugin the y value to either equation ( I will choose first equation)
3x + 5(8) =70
3x+ 40 = 70
3x = 30
x = 10
Senior tickets are $10, child tickets are $8
