Answer:
The number of student tickets sold was 105
Step-by-step explanation:
Let
x ----> the number of student tickets sold
y ----> the number of adult tickets sold
we know that
If total of 230 tickets are sold for $825
then
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The solution is the point (105,125)
see the attached figure
therefore
The number of student tickets sold was 105
Exact Area = pi square units
Approximate Area = 3.14 square units
=========================================
Work Shown:
The full circle area is pi*r^2 = pi*2^2 = 4pi
This quarter circle has area (4pi)/4 = pi square units
This is approximately equal to pi = 3.14
Answer:
x = -5
Step-by-step explanation:
g(x) = -3x+1
g(x) = -3(-5) + 1
g(x) = 15 + 1
g(x) = 16
Answer:

Step-by-step explanation:
We know that
and
, so since 22 is closest to 25, then we can say that 
3 + 3 + 3 + 3 + 5 + 5 = 22
the perimeter is 22 cm
