If x+3/3=y+2/3, then x/3= <br> A) y/3<br> B)y-1<br> C)y/2<br> D)y+1

Vlada [557]

Answer:

y/2

Step-by-step explanation:

x+3=y+2

------ --------

3 2

Using cross products

2(x+3) = 3(y+2)

Distribute

2x+6 = 3y+6

Subtract 6 from each side

2x+6-6 = 3y+6-6

2x= 3y

Divide each side by 2

2x/2 = 3y/2

x = 3/2 y

We want to find x/3

Divide each side by 3

x/3 = 3/2 y * 1/3

x/3 = 1/2 y

the mass of the sun is 2 x 10^30kg and the mass of earth is 6 * 10^24 kg. Approximately how many times greater is the mass of th

german

Answer:

The mass of sun is 333333.33 times greater than the mass of earth

Step-by-step explanation:

Given as :

The mass of the sun = $2\times 10^{30}$ kg

The mass of earth = $6\times 10^{24}$ kg.

Let The mass of sun is x times greater than the mass of earth

i.e The mass of sun = x × The mass of earth

or, $2\times 10^{30}$ kg = $6\times 10^{24}$ kg × The mass of earth

Or, x = $\dfrac{2\times 10^{30}}{6\times 10^{24}}$

Or, x = $\dfrac{2\times 10^{6}}{6}$

∴ x = 333333.33

So, The mass of sun = 333333.33 × The mass of earth

Hence, The mass of sun is 333333.33 times greater than the mass of earth Answer
