Geometric mean between 9 and 36

nlexa [21]

I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.

Helen bought notebooks and pencils for school. The number of pencils she bought is given by 6(n-3) , where n is the number of no

pychu [463]

So the number of pencils bought can be represented by an equation: $P=6(n-3)$ , where n is the number of notebooks bought. Since Helen bought 5 notebooks, simply plug 5 into n: $P=6(5-3)=6(2)=12$ . So Helen bought 12 pencils.
