2,3.4,6,7,8. I think that's it from 2-10.
Hello there n ÷ 5 - 9 = 2!
Here's how i solved it:
The quotient of a number and -5, decreased by 9, is 2
"is 2" means the result is 2, so we can have one side of the equation set up to look like this: = 2.
The quotient of a number and -5, decreased by 9, is 2
This looks like: n ÷ 5
The quotient of a number and -5, decreased by 9, is 2
We are taking 9 away from the previous expression, so n ÷ 5 - 9
Putting it all together, we have: n ÷ 5 - 9 = 2
Step-by-step explanation:
We will prove by mathematical induction that, for every natural
,
We will prove our base case, when n=4, to be true.
Base case:

Inductive hypothesis:
Given a natural
,
Now, we will assume the induction hypothesis and then use this assumption, involving n, to prove the statement for n + 1.
Inductive step:

With this we have proved our statement to be true for n+1.
In conlusion, for every natural
.
Answer:
The equation you need for 3 is the volume of a sphere.
Then divide 12 by 2 to get the radius, which gives you 6, then insert this into the equation, and the answer you get for 3 is 904.78cm cubed. 904.8 (4 Significant figures) cm cubed.
