First, let's define your variables!
x=cost of tickets for adults
y=cost of tickets for kids...
You know that they sold 900 tickets, which means the combination of x and y equals 900.
Therefore one equation is...
x+y=900
We also have to take care of the second equation...
We know that 13x represents the total cost of ADULT tickets
We know 7y represents the total cost for the children...
Which means...
13x+7y=11000
There are you equations! (bolded)
Answer:
C
Step-by-step explanation:
Area of the triangle is cm^2 which makes A and D not true.
Formula
Area = 1/2 * b * h
b = 7
h = 5
Area = 1/2 * 7 * 5
Area = 1/2 35
Area = 17.5 cm^2
Answer:
O = (3,3)
Explanation:
The <em>altitude</em> of a triangle is the perpendicular from a vertex to the opposite side.
The orthocentre (O) of a triangle is the point where the three vertices intersect.
We must find the equations for only two of the altitudes, because the third will also intersect at that point.
===============
Your three points make a right triangle.
The altitude of B is side AC.
The altitude of C is sde AB.
Their point of intersection at A (3,3) is the orthocentre of thetriangle.
D I think of not then someone else can tell u
