13. G is inversely proportional to a^2
9*(-3)^2 = 25a^2
81/25 = a^2
± 9/5 = a

14.The density (d) of a substance is inversely proportional to the volume (v), of the sample
If aluminum has a density of 2.71 grams/cm^3, What would be the mass of a 20 cubic centimeter sample?
2.71 = k/20
}
54.2grams = k(mass)
