How can you make this into a fraction 0.33

Answers

33/100

Your friend has owned a dog for 9 years. This is one year less than twice as long as he has owned a cat. How long has your friend owned a cat?

Answers

Answer:

He has owned a cat for 5 years.

Step-by-step explanation:

He has owned a dog for 9 years, and this time is one year less than twice as long as he has owned a cat.

So, we can express this like:

$9=2x-1$

Solving for $x$ :

$9+1=2x\nx=(10)/(2)=5$

Therefore, he has owned a cat for 5 years.

your friend has owned a cat for 17 years, because 9 times 2 subtracted by 1 equals 17
