37-(y-19)=2y this is a problom from rsm

ankoles [38]

Answer:

y = 56/3

Step-by-step explanation:

Distribute:

37 - (y - 19) = 2y

37 - y + 19 = 2y

Add the numbers:

37 - y + 19 = 2y

56 - y = 2y

Rearrange the terms:

56 - y = 2y

-y + 56 = 2y

Solution:

y = 56/3

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
