Answer:
12 sides
Step-by-step explanation:
Given
Sum of interior angle = 1800 degrees
Required
Number of sides of the polygon
The sum of interior of a convex polygon is calculated using the following formula:
Sum = (n - 2) * 180
Where n is the number of sides of the polygon.
By substituting 1800 for Sum, we have
Divide through by 180
Add 2 to both sides
Re order
Hence, the number of sides of the polygon is 12
Answer: well if you want to subtract then the answer would be 3.375 and adding it would be 11.375
Answer:
8 students for every teacher
Step-by-step explanation:
112 divided by 14 is 8
The value of x from the given parameters is x = -1/7
<h3>How to determine the value of x?</h3>
The given parameters are:
Point E is between points D and F
DF = 18x - 1
DE = 3x + 5
EF = -x - 8
The statement point E is between points D and F, means that
DF = DE + EF
Substitute the known values in the above equation
So, we have:
18x - 1 = 3x + 5 + x - 8
Collect the like terms
So, we have
18x - 3x - x = 5 - 8 + 1
Evaluate the like terms
14x = -2
Divide both sides by 14
x = -1/7
Hence, the value of x from the given parameters is x = -1/7

Answer:
"=" and "<"
Step-by-step explanation:
|9| = |-9|
|9| and |-9| indicates the absolute value of 9 so we use equality sign
7.5 = 7.50
7.5 is equal to 7.50 adding zeros to the right side of an expression won't change its quantity
For example:
I say I have 7.5 dollars and my friend says he has 7 dollars and 50 cent
We have same amount of money.
-3.31 is smaller than -3.13 because it's further from point zero in number line so we use < for this expressions.
