Answer:
2/3
Step-by-step explanation:
You first multiply 4x1/3 which equals 4/3. Now you do -2/3+4/3=2/3. Hope this helps!
Step-by-step explanation:
3(x - 3) + 2x + 9 - 2x + 2(x - 1)
3x - 9 + 2x + 9 - 2x + 2x - 2
Solving like terms
5x - 2
5x = 2
x = 2/ 5
I think she incorrectly applied the multiplication and division properties of equality
If 
than 
however any 
divided by 2 is in 
.
But it is not so simple.
If 
is odd then 
is even but when even number is divided by 2, you get an odd number which is in .
However if is even then is odd and when we divide that by 2, you get a number like for example 
which is not in but rather inside . There are fortunately no irrational numbers.
There is also a problem with zero, zero is neither odd nor even but still an integer. If your happens to be -1, 
, and zero divided by 2 is still just 0 which is in .
So to sum up,
If is odd and not -1, then 
.
Or to put it in math 
.
If is even or -1, then 
.
Or to put it in math 
.
<u>Notes</u>:
is a set of integers.
is a set of rational numbers.
means integers are a subset of rational numbers, that is, every integer is a also a fraction, however not every fraction is an integer.
Hope this helps :)
