Answer:
5.5 years old.
Step-by-step explanation:
Let D represent present age of Robert's dog and C represent present age of Karen's cat.
We have been given that Robert's dog is 4 years older than Karen's cat. We can represent this information in an equation as:
We are also told that in 3 years, the sum of the ages of Robert's dog and Karen's cat will be 13. After 3 years age of dog and cat would be and
respectively.
We can represent this information in an equation as:
From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Combine like terms:
Therefore, Robert's dog is 5.5 years old right now.
Answer:
Step-by-step explanation:
From the question we are told that:
Data
Generally the equation for Point estimate is mathematically given by
When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number: 
. in our rational number the denominator is 1, and the numerator is 3
Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation:
. In this case, the numerator is 4, and the denominator is 
.
We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span>.
