I assume you're looking for n.
so, take 2n/10-3n/10=2/10. Making everything have the same denominator is always easier.
This way, you have -n/10=2/10.
n=-2.
Answer:
c < -1
Step-by-step explanation:
There is an open circle at -1 That means it is not equal to
The line goes to the left
That means less than
c < -1
18
Step-by-step explanation:
X-3=15
Make X the subject of the formular by transferring the number with co-efficients in one side if the equation.
X=15+3
X=18
Answer:
D : {x ∈ R : x≠1}
Step-by-step explanation:
The domain is what values of x can we put into the function and it still works
We cannot have the denominator equal zero
x-1 ≠0
Add 1 to each side
x-1+1 ≠0+1
x≠1
The domain is all real values of x except x=1
D : {x ∈ R : x≠1}
