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

Answer:
<h2>Factor perfect squares out of the square root until there are no more perfect squares inside.</h2>
Step-by-step explanation:
<h2>Begin by working inside the square root itself. You can manipulate the interior of the square root as much as you'd like so long as you don't violate any other rules of algebra. </h2>
<h2>√160=√16⋅10</h2>
<h2>Because 16 is a perfect square, we can pull it out of the square root as a 4.</h2>
<h2>That will simplify down to 4√10</h2>
<h2>because there are no additional perfect square factors in 10, the resultant is simplified.</h2>
<h2>Therefore, √160 simplifies to 4√10</h2>
Answer:
50 minutes
Step-by-step explanation:
it takes 80 minutes for 5 pipes
so for 1 pipe it will take 5x80=400min
and for 8 pipes it will take 400/8=50min
Answer:
