PLEASE HELP!!!

Mathematics
1 answer:
Sholpan [36]3 years ago
8 0

Answer:

You have to replace x for each density

Step-by-step explanation:

Density = Mass / Volumen

1,000 g = 1 kg

1,000,000 cm^3 = 1 m^3

g/cm^3 = 1000 kg/m^3

Using density as x

volumen \:  =  \frac{50000}{x}  \\ volumen  \: sphere \:  = 4\pi {r}^{3}  \\ 4\pi {r}^{3}  =  \frac{50000}{x}  \\ r =  \sqrt[3]{ \frac{50000}{4\pi {x}^{} } }

Kryger [21]

The cash flow in year 1 is $15.

<h3>What is the cash flow in year 1?

Help ..<br><br><br><br> 3(x+2)=5x+1-2x+5
Hunter-Best [27]

Answer:

All real numbers are solutions

Step-by-step explanation:

Let's solve your equation step-by-step

3(x+2)=5x+1−2x+5

Step 1: Simplify both sides of the equation

3(x+2)=5x+1−2x+5

(3)(x)+(3)(2)=5x+1+−2x+5(Distribute)

3x+6=5x+1+−2x+5

3x+6=(5x+−2x)+(1+5)(Combine Like Terms)

3x+6=3x+6

3x+6=3x+6

Step 2: Subtract 3x from both sides

3x+6−3x=3x+6−3x

6=6

Step 3: Subtract 6 from both sides

6−6=6−6

0=0
