Answer:
2500 kg/m³
Step-by-step explanation:
Density of a material is the ratio of mass and volume of that material.
The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)
Given density as 2.5 g/cm³ , convert to kg/m³
Formula is;
1g/cm³ = 1000 kg/m³
2.5 g/cm³=? cross-multiply
=2.5×1000 = 2500 kg/m³
8 is to 64 as 2 is to 16
x=16
3w-7w-12=2w-6
-4w-12=2w-6
-12=6w-6
-6=6w
w=-1
The missing number is 20.
<h3>What is the missing number?</h3>
Subtraction is the mathematical operation that is used to find the difference between two or more numbers.
