H = positive (14) because -98 / -7 is 14
U = is (-144) because it has u multiply 6 instead of dividing to remove it. If you do it ot one side you must do it to all other sides.
Q = 18 * 5 is (90)

Answer:
Volume of emerald = 137.04cm³
Step-by-step explanation:
Given that:
Mass of emerald = 378.24grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 378.24grams / 2.76grams/cm³
Volume of emerald = 137.043cm³ ~137.04cm³
Volume of emerald =137.04cm³
