Answer: 16.26 g.

To answer this question, you just need to multiply the volume with the density. In most question, the unit of the volume and density is different thus need to be converted. But in this question, it's already same so you can do it straight away. The calculation would be:

Mass: 6 cm3 x 2.76g/cm3= 16.26 g.

Solve the system of equations.

lys-0071 [83]

Step-by-step explanation:

Solve the system via elimination (add the equations):

-10y + 9x = -9

+ (10y + 5x = -5)

-----------------------

14x = -14

x = -1

Plug in the value for 'x' into the second equation:

-10y + 5(-1) = -5

Solve for y:

-10y - 5 = -5

--> -10y = 0

--> y = 0

x = -1

y = 0
