First of all, you should know/notice that

You should also know how negative exponents work:

So, if you wanted

the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:

Im pretty sure the answer is a
906 grams.
1000-94=906 grams
Changing improper fractions to mixed
form or mixed numbers is a very simple thing. You just have to follow the following:
Then write
Let us have 25/8.
<span><span>
1.
</span><span>Divide the numerator (top
number) by the denominator (number below
the bar). </span></span>
Simply divide 25 by 8.
25 ÷ 8 = n
We can have 3 and 1 as a remainder. So, the
answer will be 3 and 1/8.
<span><span>
2.
</span> <span>Write down the whole number answer.
Since we have 3 as the whole number answer,
write it down. And;</span></span>
<span><span>
3.
</span><span> Write down any remainder above the denominator,
like this:</span></span>
3 and 1 (remainder) over 8
(denominator of the given improper fraction).
That is, 3 1/8
Answer: C
It’s going down by the same rate of change, 2.
