Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
_____
The solution can be found any number of ways. It is
(a, c) = (232, 87)
A = 0.5 x 10.4 x 16.9
A = 87.88
The area of the triangle is 87.88 ft²
Answer:
Geometry (from the Ancient Greek: γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer.

I want the phone so your answer is simple
7+4+4= 15
15-4=11
you answer is 11:4
Hello!
1.
The area of a rectangle is lenth * width
So 16 * 6 = 96
------------------------------------------------------------------------------------------------------
2.
The area of a square is a side^2
So 11^2 = 121
------------------------------------------------------------------------------------------------------
3.
The area of a parallelogram is base * height
So 14 * 9 = 126
------------------------------------------------------------------------------------------------------
4.
It is a parallelogram again
So 12 * 8 = 96
------------------------------------------------------------------------------------------------------
5.
The area of a triangle is
h is height and b is base
15 * 19 = 285
285/2 = 142.5
------------------------------------------------------------------------------------------------------
for number 6 I do not remember how to do that sorry
Hope this helps!<span />
