Answer:
2.7715 x 10^9 miles
Step-by-step explanation:
The distance from Mercury to the sun is 28.5 million miles which is 28.5 x 10^6 miles.
The distance from Neptune to the sun is 2.8 x 10^9 miles.
Then we know that:
Distance Neptune-Sun = Distance Neptune-Mercury + Distance Mercury-Sun
Solving for 'Distance Neptune-Mercury" we have that:
Distance Neptune-Mercury = Distance Neptune-Sun - Distance Mercury-Sun
Distance Neptune-Mercury = 2.8 x 10^9 miles - 28.5 x 10^6 miles.
Distance Neptune-Mercury = 2,771,500,000 miles
Which can be expressed: 2.7715 x 10^9
