Light travels at 5.87x10^12 miles in one year if a star is 2x10^4 light years away, how many miles away is that star?

1.174x10^17 miles

Step-by-step explanation:

5.87x10^12 x 2x10^4.

(5.87x2)(10^12x10^4)

=11.74(10^16)

In Sci. Not., you cannot have a number less than 1 or greater than 10, so multiply these numbers together and move the decimal one to the left.

Your final answer should be 1.174x10^17 miles.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

your answer would be 12
