Answer:

-53

Step-by-step explanation:

Since x= -12 you would have to replace the x in the equation with -12. (Start with 3x-17 End up with 3(-12) -17 ) So after replacing x with -12 you would solve. 3* -12= -36 and -36 -17= -53. So after all of that, your final answer would be -53.

A block of iron has a mass of 3152 kg and a volume of 0.4 m².Calculate the density of the block of iron, in kg/m3.

Lisa [10]

The density of the block of iron in $kg/m^3$ is equal to 7,880.

<u>Given the following data:</u>

Mass of block = 3152 kg

Volume of block = 0.4 $m^2$

To calculate the density of the block of iron in $kg/m^3$ :

<h3>What is density?</h3>

Density can be defined as mass all over the volume of an object or body. Thus, density is equal to mass per unit volume of an object.

<h3>How to calculate density</h3>

Mathematically, the density of a substance is given by this formula;

$Density =\frac{Mass}{Volume}$
