Answer:
- [tex]\boxed{\sf{r=9}}[/tex]
Step-by-step explanation:
To find the value of r, isolate it on one side of the equation.
[tex]\sf{2r+8=26}[/tex]
First, you have to subtract by 8 from both sides.
[tex]\sf{2r+8-8=26-8}[/tex]
Solve.
Subtract the numbers from left to right.
26-8=18
2r=18
Divide by 2 from both sides.
[tex]\sf{\dfrac{2r}{2}=\dfrac{18}{2} }[/tex]
Solve.
Divide the numbers from left to right.
18/2=9
r=9
- Therefore, the correct answer is r=9 meters.
