37.9 equals 30+7+.9 you should try to put in number form so you know what you're dealing with
We have to give counter example for the given statement:
"The difference between two integers is always positive"
This statement is not true. As integers is the set of numbers which includes positive and as well as negative numbers including zero.
Consider any two integers say '2' and '-8'. Now, let us consider the difference between these two integers.
So, 2 - 8
= -6 which is not positive.
Therefore, it is not necessary that the difference of two integers is only positive. The difference of two integers can be positive, negative or zero.
The square root of 9800=
= 70 * square root of 2
Start by putting two coins on each side of the scale. If one side is higher, then the light coin must be in that pair (use a second weighing to determine which of that pair is the lightest.)
If the initial weighing shows the two pairs to be even, discard those four and go to the three others. Put two of the coins on the scale - one on each side. If one side stays higher, that coin is your light one. If however they are equal, the final unweighed coin must be the lighter coin.
Answer:
the answer is 4y-2
Step-by-step explanation:
To simplify any algebraic expression you need to add liketerms.
In this equation, the liketerms are y and 3y.
3y+y= 4y
We are left with 4y-2; we cant go any further, because 4y and -2 are not liketerms.
