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
