The distance from Earth to the sun, about 1.50 x 10^8 kilometers, is known as an astronomical unit. The nearest star, Proxima Centauri, is 2.6 x 10^8 astronomical units from Earth. How many kilometers separate Earth from the nearest star? Write you answer in Scientific Notation

Distance from Earth to Proxima Centauri (in scientific notation) = kilometers

Step-by-step explanation:

We need the conversion between Astronomical Unit and Kilometers.

The conversion is:

1 AU = 1.496*10^8 km

or rounded, given in this problem,

1 AU = km

We need the distance from Earth to Proxima Centauri:

AU * kilometers

When multiplying two numbers in scientific notation, we have to "multiply the coefficients" and "add the exponents".

Lets do this:

Distance from Earth to Proxima Centauri (in scientific notation) = kilometers

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

9 x 8 divided by (5-3)=36
