Answer:
The equation that represents the given situation is 5(x - 3) = 20.
Step-by-step explanation:
The mathematical formula states that if 3 is subtracted from a number (let's call it x) and the difference is multiplied by 5, the result is 20.
To represent this situation in an equation, we start with the number x. When we subtract 3 from it, we get (x - 3). Then, we multiply this difference by 5, which gives us 5(x - 3). Finally, we set this expression equal to 20, resulting in the equation 5(x - 3) = 20.
