Answer:
The two numbers are 6 and 12.
Step-by-step explanation:
So, let's start off, with x+y = 18 and x-y = 6.
Algebraically, we can add the above two equation sets, and we find out that 2x = 24, so x = 12. And then, it says the other number must be 6.
You start with a number that when added to the second number you will get 18 and when you subtract the second number from the first you will get 6. The difference between the above two results is 12.
So that difference of 12 is twice the second number; that means the second number is 6. And then using either of the given pieces of information, you can find that the first number is 12.
------------------------------------------------------
In conclusion:
6 + 12 = 18
12 - 18 = 6
The answer is B. the open circle means “greater than” or “less than” and the closed circle means “greater than or equal to” or “less than or equal to”.
Answer:
(a) |ab| if a<0 and b>0
since the modulus of a number no matter whether it is positive or negative gives the result as a positive number.
if a<0 and b>0 then ab<0
this implies ab is a negative number and modulus of negative number comes out to be positive term.
<em>eg:</em> if a= -2 and b=3
Then ab= -6
and |ab|=|-6|=6
(b) |ab| if a>0 and b>0.
since both a and b are positive numbers i.e. strictly greater than zero.
hence, ab>0
eg: if a=5 and b=2
then ab=10
and |ab|=|10|=10
