lesya692 [45]
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

What does it mean when there is a number above and below a dash in algebra?
AleksAgata [21]

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  

page, Final Answers by Gerard P. Michon:

A cone and cylinder have the same height and their bases are congruent circles. If the volume of the cylinder is 120 cubic inche
NikAS [45]

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

If 1=3 2=3 3=5 4=4 5=4 then 6=?​
Mama L [17]

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.

Ganezh [65]

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
