A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?
Drupady [299]

Answer:

16.56\ g

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

Let

x-----> the mass of marble

y----> the volume of marble

z----> the density of marble

z=\frac{x}{y}

in this problem we have

y=6\ cm^{3}

z=2.76\ g/cm^{3}

substitute and solve for x

2.76=\frac{x}{6}

x=2.76*6=16.56\ g

Y-3=2(x+1)<br> Can you guys please help me solve for y
Tatiana [17]

Answer:

First, you have to rewrite the question in a way to isolate your Y. This means moving the -3 over to the other side.

Y = 2(x+1) + 3

Now, you should multiply the 2 out in the parenthesis.

Y=2x+2+3

Now, combine like terms! In this case, your like terms are 2 and 3.

Y=2x + 5

Because there are no more like terms, and Y is completely isolated, Y=2x + 5 is your answer!
