13.00 I think I don’t know if that correct but that’s what I got
we have

Adds
both sides


square root both sides

therefore
<u>the answer is</u>
the resulting equation is 
We'll let x represent the weight of Ian's dog.
So we can make the formula Ian's dog (x) + Stephen' dog (5x) = 72
So:
x+5x=72
6x=72
x=12
So ian's dog is 12 pounds, but we're trying to find stephen's dog (5x)
We need to multiply x by 5 so:
5(12)=60
Therefore, Stephen's dog is 60 pounds
Solution :
The minimum distance from Earth to the Sun is 91.4 million miles
The maximum distance is 94.5 million miles



d=92.95



Absolute Value Equation:
|x - d| = 
|x - 92.95| = 1.55
