The maximum distance the earth is from the sun is 152,000,000 Km and the minimum distance is 147,000,000 Km. Write an absolute value equation where d represents the maximum and minimum distance between earth and the sun in millions of kilometers.

Question

anonymous · Answer

Poorly worded question.  If d represents the distance from earth to sun as a function of time, d(t), $$147 \le d(t) \le 152$$ in millions of km.

You forgot about the absolute value part of the question

anonymous · Answer

absolute value is the distance away from 0
 so it would be 147 mill and 152 mill its basically a waste of time. thanks albert

anonymous · Answer

Since distance is always non-negative, there is no need for an absolute value.

anonymous · Answer

I say again, this is a poorly worded question.

$$\left| d-149,500,000 \right|\le2,500,000$$

anonymous · Answer

oops
 
|d−149.5|≤2.5
didn't seethe millions part

anonymous · Answer

If it's going to be an equation, you need it to be equal.  That means when you solve for d, you will get the two numbers given in the problem.

Nice work.  I never would have seen it that way.
