Answer:
Option 2nd , 4th and 6th correct
[tex]-2b[/tex], [tex]\frac{b}{12}[/tex] and [tex]-0.9b[/tex]
Step-by-step explanation:
Like terms are those terms which have same variable to the same power.
Given the expression:
[tex]\frac{5}{6}a-2b-16.3+\frac{b}{12}+c-0.9b[/tex]
Combine like terms;
[tex]\frac{5}{6}a+b(-2+\frac{1}{12}-0.9}-16.3+c[/tex]
Simplify:
[tex]\frac{5}{6}a-2.81666667b-16.3+c[/tex]
Therefore, the term can be combined in the given expression is,
[tex]-2b[/tex], [tex]\frac{b}{12}[/tex] and [tex]-0.9b[/tex]
