Answer:

The density of cube is 6.17959 \frac{g}{cm^{3} }

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

\rho = \frac{m}{V}

Where,

\rho is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V=0.53^{3}=0.148877cm^{3}

Now, the Density of the cube will be

\rho = \frac{m}{V}

\rho = \frac{0.92}{0.148877}

\rho =6.17959

Thus, The density of cube is 6.17959 \frac{g}{cm^{3} }

Please help me solve 3x + 4y =15 and 3x - y = 30 it is for Algebra I
Makovka662 [10]

Answer:

Step-by-step explanation:

Given the simultaneous equation

3x+4y=15. Equation 1

3x-y=30. Equation 2

Using elimination method

Sutract equation 2 from 1

Then, will have

3x-3x+4y--y=15-50. -×-=+

4y+y=-15

5y=-15

Divide Both sides by 5

y=-15/5

y=-3

From equation 2

3x-y=30

3x--3=30

3x+3=30

3x=30-3

3x=27

Divide both side by 3

x=27/3

x=9

Then, x=9 and y=-3
