If 5a = 3125, then the value of 5(a - 3) is:251256251625

First, we need to find the value of 'a'. We can do this by rearranging the equation 5a = 3125 to solve for 'a'.

Step 1: Divide both sides of the equation by 5.

a = 3125 / 5

Step 2: Calculate the value of 'a'.

a = 625

Next, we substitute 'a' into the equation 5(a - 3) to find the value.

Step 3: Substitute 'a' into the equation.

5(a - 3) = 5(625 - 3)

Step 4: Simplify the equation.

5(a - 3) = 5(622)

Step 5: Calculate the value.

5(a - 3) = 3110

So, the value of 5(a - 3) is 3110.
