Evaluate 25- 4y, when y=5

5

Step-by-step explanation:

25-4y

25-4(5)

25-20

5

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.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
