The expression x + 20 - 1 can be evaluated as follows:
x + 20 - 1 = 9 + 20 - 1 = 29 - 1 = 28
So the correct answer is 28.
To evaluate the expression x + 20 - 1, we substitute x = 9 into the expression:
9 + 20 - 1
Next, we simplify the expression by performing the addition first:
29 - 1
Finally, we perform the subtraction:
28
So the value of the expression x + 20 - 1, using the given values, is 28.
To evaluate the expression x + 20 - 1 using the given values, we replace x with 9 and simplify accordingly.
So, the expression becomes 9 + 20 - 1.
Now, we can solve it step by step:
9 + 20 = 29
29 - 1 = 28
Therefore, the value of the expression x + 20 - 1 is 28.
So, the correct answer is 28.
