Evaluate a-13 when a=33

To evaluate a-13 when a=33, we substitute the value of a into the expression:

a - 13
= 33 - 13
= 20

Therefore, when a=33, a-13 equals 20.

To evaluate a-13 when a=33, simply substitute the value of a into the expression and perform the subtraction:

a - 13 = 33 - 13

Now, subtract 13 from 33:

33 - 13 = 20

Therefore, a-13 is equal to 20 when a=33.

To evaluate the expression "a - 13" when a equals 33, substitute 33 in place of the variable a in the expression.

So, "a - 13" becomes "33 - 13".

Now, subtract 13 from 33:
33 - 13 = 20.

Therefore, when a equals 33, the value of "a - 13" is 20.
