Answer:
The correct option is B. b= 4.2
Step-by-step explanation:
Consider the provided information.
We need to solve the equation for b.
Solve the equation for b as shown:
[tex]b+8=12.2[/tex]
Subtract 8 from both the sides to isolate the variable b.
[tex]b+8-8=12.2-8[/tex]
[tex]b=4.2[/tex]
Hence, the value of the equation for b is 4.2
The correct option is B. b= 4.2
