Answer:
Brain is 3 years old.
Step-by-step explanation:
Let B represent Brain's age and D represent Dane's age.
We have been given that Dane is 10 times Brian's age. We can represent this information in an equation as:
[tex]D=10B...(1)[/tex]
We are also told that the difference in their age is 27. We can represent this information in an equation as:
[tex]D-B=27...(2)[/tex]
Upon substituting equation (1) i equation (2), we will get:
[tex]10B-B=27[/tex]
[tex]9B=27[/tex]
[tex]\frac{9B}{9}=\frac{27}{9}[/tex]
[tex]B=3[/tex]
Therefore, Brain is 3 years old.
