Answer and Step-by-step explanation:
To translate the given sentence into an equation, we can use the variable r to represent Rick's age.
The difference of Rick's age and 7 can be represented as "r - 7". The phrase "is 55" indicates that this difference is equal to 55. Therefore, the equation can be written as:
r - 7 = 55
In this equation, r represents Rick's age. By subtracting 7 from his age, we are finding the difference between his age and 7. And since this difference is given as 55, we set the equation equal to 55.
This equation can be solved to find the value of r, which will give us Rick's age. To solve it, we can add 7 to both sides of the equation:
r - 7 + 7 = 55 + 7
Simplifying, we get:
r = 62
Therefore, Rick's age is 62.
