1. 31,150 = x * 25,300
.. x = 31,150/25,300 = 1.231225... ≈ 1.23
Gary's 2017 salary is 1.23 times his 2015 salary.
2. 1.23 * 100% = 123%
Gary's 2017 salary is 123% of his 2015 salary.

Answer:
9m
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2 where s is the side length
We know the surface area is 486 and the side length is z
486 = 6z^2
Divide each side by 6
486/6 = 6z^2/6
81 = z^2
Take the square root of each side
sqrt(81) = sqrt(z^2)
9 = z
Each side has a length of 9m
