First simplify. Combine like terms
-6n + 3n = -3n
-3n = -18
Isolate the n, divide -3 from both sides
-3n/-3 = -18/-3
n = -18/-3
n = 6 (remember, in dividing two negative numbers, the answer will be positive).
6 is your answer

Answer:
961
Step-by-step explanation:
5 apples and 6 pears are to be distributed among 3 different people.
the number of ways the fruits could be distributed without restrictions is 3^ 11 = 177147
If each person gets at least one pear,first calculate the number of ways 6 pears could be distributed among 3 people
= 3^6 - 3
= 729 -3 = 726
Secondly calculate the number of ways 5 apples could be distributed among 3 people
3^5 = 243
Total = 726 + 243
= 961 ways
I'm assuming you're subtracting. It would be 3.9. The second one would be 0.65.
Answer:
The number that would go in the blank to get a perfect square trinomial is 18
Step-by-step explanation:
The middle term can always be found by taking twice of the square root of the final term.
2 * √81 = 18
