which can be written as -sqrt(25) on a keyboard, can be simplified to -5 since the square root of 25 is 5.
Put another way, 5^2 = 25 so we're simply going in reverse.
So the question is: where does -5 belong? Which number set?
The answer is: the set of
integers and
rational numbersSo that's the two
answers----------------------------------------------------------------------------------
Extra Info:
The value -5 is not a natural number as the set of natural numbers is {1, 2, 3, 4, 5, ...} basically the set of counting numbers
The same story applies to the set of whole numbers which is {0, 1, 2, 3, ...}
So -5 is not in the set of whole numbers
The value -5 is also not irrational because it is rational. We can write it as a ratio of two integers: -5 = -5/1
First put them in order from smallest to the largest
which is:
15, 31, 62, 82, 95, 98,103
the median is the one in the middle so that is
=82
<span>x=52</span>
<span><span>x8</span>−<span>12</span>=6</span>
<span><span><span>2x−8</span>16</span>=6</span>
<span>2x−8=6⋅16</span>
<span>2x=96+8</span>
<span>2x=104</span>
<span>x=<span>52</span></span>
That’s not 25 points but ok
