what's up? this answer is B, 72

we can figure out that one third of melissa's age is 24 because 18+6= 24. simply eliminate the obvious incorrect answers, A and C. 78/3= 26 so it isn't D
72/3=24 it is B

best of luck with your studies

Answer:

B. 72

Step-by-step explanation:

Adam (A): 18

Melissa (M):?

[tex]A=\frac{m}{3} -6[/tex]

[tex]18=\frac{m}{3} -6[/tex]

[tex]24=\frac{m}{3}[/tex]

[tex]m=4(3)=72[/tex]

Therefore, Melissa is 72 years old.

Hope this helps!
