<h3>The height of the tree is 55 feet</h3>
<em><u>Solution:</u></em>
Let,
Height of tree = x
Shadow of tree = 40 feet
Height of man = 5.5 feet
shadow of man = 4 feet
Set up a proportion comparing the height of each object to the length of the shadow.

Therefore,

Thus height of the tree is 55 feet

x
You can put that on a number line. Be sure that the dot you use is closed.
Answer:
think it is D
Step-by-step explanation:
look at the X axis and the number at the Y axis
The algebraic solution to the situation is as follows:
x + y = 750
10x + 6y = 6860
The number of adult and student are 590 and 160 respectively.
<h3>How to find and solve an algebraic equation?</h3>
One adult ticket for a school play costs 10 dollars and one student ticket costs 6 dollars.
One evening,750 people attended the play and the total receipts were 6860.
Therefore,
let
x = number of adult ticket
y = number of student tickets
Therefore,
x + y = 750
10x + 6y = 6860
10x + 10y = 7500
10x + 6y = 6860
4y = 640
y = 640 / 4
y = 160
Hence,
x = 750 - y
x = 750 - 160
x = 590
