Answer: 20
Step-by-step explanation: Here, we have the expression 25 - 4y and we want to evaluate the expression when y is equal to 5.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since y is equal to 5, we have 25 - 4(5).
4(5) is equal to 20 so we have 25 - 20 which is equal to 20.
So the value of our expression when y is equal to 5 is 20.
