Answer:
Well If there are answer choices please place them in the comments. But if there are not, that's okay. I'd say that you'd just keep it at 5,900 if you are trying to round to the nearest hundred. If you are trying to round to the nearest thousand, 6,000 would be right.
Remember, if the number is or is between 1 and 5 round down but if it is or is between 5 and 9, round up.

So we have the following system of equations:
We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:
So y=-1. If we use this value in the second equation:
So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
Answer: 6.403 miles; or, write as: 6.403 mi. .

__________________________________________________
Since we have a "right triangle, we solve for "c"; using the
"Pythagorean theorem" ;
_______________________________________________________
→ a² + b² = c² ; Solve for "c" ; our answer (in "miles"; or, "mi.") ;
__________________________________________________
Given : a = 4; b = 5 ;
____________________________
Plug these known values into our equation:
________________________________________
→ 4² + 5² = c² ;
____________________________
→ 16 + 25 = c² ; ↔ c² = 16 + 25 ;
______________________________
→ c² = 41 ;
_______________________________
→ Take the positive square root of each side of the equation (since the side of a "triangle" cannot be "negative";
__________________________________
→ √(c²) = √(41) ;
_____________________________
→ c = √41 ; Use calculator;
________________________________
→ c = 6.40312423743 ; Round to:
→ c = 6.403 miles; or, 6.403 mi.
