Step-by-step explanation:
4x+x-1+2x+1
since any number power zero is one
group like terms
4x +x+ 2x-1+1
7x=0
divide both sides by 7
x= 0
How many was to make49 out of ones and tens
Transitive.
Associative is (a + b) + c = a + (b + c)
Commutative is a + b = b + a
Reflexive is a = a
Thus, transitive is the correct answer.
Hope this helps!
The answer is B because you have to skip number until you get to the first number and you skipped 9 times so it 10^9
