Question

9 + 9 - p; use p = 1, and q = 1

Answer 1

To solve the expression 9 + 9 - p with p = 1, you substitute the value of p into the expression, simplify it by adding 9 + 9 to get 18, and then subtract 1 to end up with the final answer, which is 17.

Step-by-step explanation:

The student has asked to evaluate the expression 9 + 9 - p using p = 1, and though q = 1 is provided, it isn't needed for this calculation. To solve this, we simply substitute the value of p into the expression, obtaining:

9 + 9 - p = 9 + 9 - 1

After substitution, we perform the arithmetic:

9 + 9 - 1 = 18 - 1 = 17

So the final answer is 17.
