Answer:

Option B - =8.4672\times 10^{13}

Step-by-step explanation:

Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles.Suppose a star is 14.4 light years from earth.

To find : In scientific notation, how many miles away a star is from earth?

Solution :

One light-year is the distance that light can travel in one year is = 5,880,000,000,000 miles.

In scientific notation, 5.88\times 10^{12} miles.

In 14.4 lights year the distance is  =14.4\times5.88\times 10^{12}

In 14.4 lights year the distance is  =84.672\times 10^{12}

                                                  or  =8.4672\times 10^{13}

Therefore, Option B is correct.

-2 (-3x + 3) + 2x = 58
dusya [7]

Answer:

x = 8

Step-by-step explanation:

Given

6x - 6 + 2x = 58

8x - 6 = 58 ( add 6 to both sides )

8x = 64 ( divide both sides by 8 )

x = 8
