Combine like terms
10/7k + 2/7k = 12/7k - 2k = 12/7k - 14/7k = -2/7k
11/7 + 2/7 - 6 = 13/7 - 42/7 = -29/7
-2/7k - 29/7 should be your answer
hope this helps

</span>Give the scientific notation of 8.7 billion.
8.7 billion = 8 700 000 000
Scientific notation is the process of multiplying the given number by 10 to the
power of n.
Since billion has 9 zeros that’s equals
to 10^9
=> 8.7 x 10^9
let’s try solving this
=> 8.7 x (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10)
=> 8.7 x 1 000 000 000
=> 8 700 000 000
Thus, our scientific notation of 8.7 billion is 8.7 x 10^9</span>
