Answer:
Step-by-step explanation:
Neptune is about 2,700,000,000 miles from Earth.
Mercury is about 135,000,000 miles from Earth.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The power is the number of decimal places you move.
1) 2,700,000,000 = 2.7 x 
135,000,000 = 1.35 x 
2)
You can see there is only one extra 0 on top, the rest will cancel so you have:
It's 20x farther to Neptune from Earth, than it is to Mercury from Earth.
A constant is a number that never changes value. Example:
x + 3 = 5, 3 and 5 are constants.
The answer would be 1.25.
