Answer: 2x -5
Step-by-step explanation:
Hi, to answer this question we have to write equations with the information given:
- <em>John has × marbles </em>
John=x
- <em>Max has twice (multiplied by 2) as many.max give gives john 5 of his marbles.
</em>
We have to multiply by 2 the number of marbles that John has (x), and subtract 5.
Max = 2x -5

Make a proportion
6/18 = 10/z
Cross multiply
180 = 6z
180/6 = z
Z = 30
The geometric mean of the numbers is 5.38
Given the values a, b, c and d
Geometric mean of the values will be expressed as:
GM = (abcd)^1/4
Given the values 4, 5, 6 and 7, the geometric mean will be expressed as:
GM = (4×5×6×7)^1/4
GM = (840)^1/4
GM = 5.38
Hence the geometric mean of the numbers is 5.38.
