Answer:
A) [tex]27 = b + 9[/tex]
[tex]b=18[/tex]
Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:
[tex]27 = b + 9[/tex]
Use inverse operations to solve this equation,
[tex]27 = b + 9[/tex]
[tex]-9[/tex]
[tex]18 = b[/tex]
