A total of 234 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answers

234 = a + s s = students a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get
234 = a + 2a
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold

Which two numbers add up to 6 and muliply to -126

Answers

xy=-126
x+y=6
minus x

y=6-x
sub
x(6-x)=-126
6x-x^2=-126
minus (6x-x^2) both sides
0=x^2-6x-126

in form
ax^2+bx+c=0
x= $\frac{ -b+/-\sqrt{b^(2)-4ac} }{2a}$

a=1
b=-6
c=-126

x= $\frac{ -(-6)+/-\sqrt{(-6)^(2)-4(1)(-126)} }{2(1)}$
x= $( 6+/-√(36+504) )/(2)$
x= $( 6+/-√(540) )/(2)$
x= $( 6+/-6√(150) )/(2)$
x= $3+/-3√(150)$

the numbers are
$3+3√(150)$ and $3-3√(150)$

The number of wolves in a wildlife preserve is estimated to have increased continually by 3% per year. If the population is now estimated at 5,400 wolves, how many were present 10 years ago?

Answers

For the answer to the question above, Well, first let us put up a functional equation.
Since this is an exponential function, it'll be: f(t)=54,000*1.03^t
But we want to know how many wolves there were 10 years ago.
For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t
This displays a decreasing number of wolves, as you turn back time.

Now we simply calculate 54,000*1.03^-10
which is approximately 40,200?
