Answer:


  • \boxed{\sf{r=9}}

Explanation:

To find the value of r, isolate it on one side of the equation.



\sf{2r+8=26}

First, you have to subtract by 8 from both sides.


\sf{2r+8-8=26-8}

Solve.

Subtract the numbers from left to right.

26-8=18

2r=18

Divide by 2 from both sides.


\sf{(2r)/(2)=(18)/(2) }

Solve.

Divide the numbers from left to right.

18/2=9

r=9

  • Therefore, the correct answer is r=9 meters.

I hope this helps. Let me know if you have any questions.
