Answer:
Yes,its true
Step-by-step explanation:
<h2>__________________</h2><h2>Consider, a number x</h2>
<h2>as per question</h2>
<h2>x+(-x) =x-x=0</h2><h2>__________________</h2>
If she has 10/12 and uses 8/12 then you just subtract.
Since the denominators are the same you just subtract 10-8 and get 2
the denominator is the same for your answers and so it is
2/12
Answer:
A
Step-by-step explanation:
this is because an input can only have one output, but an output can have many input
1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)
