Evaluate:

15+z, if z is equal to 7

What do you think?

Is it 22

Yes. :-)

Thank u

You're welcome.

To evaluate the expression 15+z, when z is equal to 7, you simply substitute the value of z into the expression and perform the calculation.

So, substitute z = 7 into the expression:

15 + 7

Now, perform the calculation:

15 + 7 = 22

Therefore, when z is equal to 7, the value of the expression 15+z is 22.
