Solution for x=5-y and x+y=15

1 answer:

7 0

It might be no solution:

steps-

x=5-y
x+y=15

substitute the x(which is the top problem) into the second one.

(5-y)+y=15

cancel it out

(5-y)+y=15
-5. -5

a negative plus a positive is gonna equal 0

-y+y=15-5

0=10

that is no solution..

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= $0.53^{3}$ =0.148877 $cm^{3}$

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 $\frac{g}{cm^{3} }$
