90 is the product of Delia's age and 5. Use the variable to represent Delia's age.

Of course

D = Delia's age

90 = D ∙ 5

5 D = 90

D = 90 / 5

D = 18

Let's represent Delia's age with the variable "x."

According to the information given, 90 is the product of Delia's age and 5.

So, we can write it as an equation:

5x = 90

Now, to find the value of x, we need to isolate it on one side of the equation. Dividing both sides by 5 will give us:

x = 90/5

Evaluating the expression on the right side gives us:

x = 18

Therefore, Delia's age, represented by the variable x, is 18 years old.

Let's use the variable "x" to represent Delia's age. According to the given information, the product of Delia's age (x) and 5 is equal to 90. We can write this as an equation:

5x = 90

To find the value of x, we need to isolate the variable on one side of the equation. We can do this by dividing both sides of the equation by 5:

5x/5 = 90/5

This simplifies to:

x = 18

Therefore, Delia's age, represented by the variable x, is 18.
