Answer:
B. 1.47*10^18
Step-by-step explanation:
Given
Distance of largest start from earth in light years = 250000
1 light year = 5880000000000 miles
So,
Distance of largest star from earth in miles = 250000 * 5880000000000
= 1470000000000000000 miles
In order to convert in scientific notation, point will be moved 18 places to the left, so the number will become:
1.47* 10^18 miles
So option B is correct..
Answer:
The solution is (2, 1).
All other ordered pairs do not work.
Step-by-step explanation:
-2x + 5y = 1
5x - 3y = 7
-10x + 25y = 5
10x - 6y = 14
19y = 19
y = 1
5x - 3(1) = 7
5x = 10
x = 2
(2, 1)
The solution is (2, 1).
All other ordered pairs do not work.
