Answer:
Step-by-step explanation:
The equation for solving for density is:
Density = mass / volume
Then plug in the values:
Density = 6 g / 12 mL
Divide and don't forget the units!
Density = 0.5 g/mL
b
1.5
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
16x=16x+1
0=1
4x+12+12x+12+5=16x+30
16x+29=16x+30
