3x-5 does not belong
Reasoning :
Plug in “1” to each X unit
3(1) -5 = -2
12(1) = 12
1 + (1) = 2
(1)2 + 5(1) + 6 = 13
all are positive except 3x-5
so 3x-5
The notation of a bar (vinculum, or overbar) over a whole number
doesn't seem to be very common. Here are some possibilities as to
what it could mean:
It is sometimes used as a grouping symbol, as in a fraction:
_____ __
3 + 1 x 5 = 20 so 67 = 67
I have also seen it used to refer to the average:
_ __
x = {1,2,6}, x = 3 so 67 = 67
(the average of one number is itself, of course).
I have also heard that it can be used to mean "1000 times whatever is
underneath", especially with Roman numerals - see the following Web

Answer:
Volume of cone = 40 in³
Step-by-step explanation:
Given:
Volume of cylinder = 120 in³
Height of cylinder = Height of cone
Radius of cylinder = Radius of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h = 120 in³
Volume of cone = (1/3)πr²h
So,
Volume of cone = (1/3)(120)
Volume of cone = 40 in³
The value of the 6 is 3.
If you write 1 in word then you will write one and if you count the letter it will give you 3
Similarly, if you write the numbers 2,3,4,5 in word and count the number you will get 3,5,4,4 respectively.
<h3>What are the counting letters?</h3>
counting Letters provides a perfect way to introduce number words to beginning readers, as well as discuss the concepts of letters and words.
So, if you write 6 in words you will write six and on counting the letter you will get 3.
Hence, 6 = 3 ans.
Therefore the value of the 6 is 3.

Answer:
2) -1
Step-by-step explanation:
it is easy
we have to first open the brackets, as it is ' - ' we have to change the sign to opposite of that of the number in the bracket and then solve it.
so the number 2 is having negative sign, we make it positive. this rule is applied only when there is a negative sign and a bracket is there.
-3-(-2)
-3+2
=-1
