Use the following values to evalaute each expression: W = 13, x = 9, Y = 1.9, Z = 0.5.

Question: X + 20 - 1.
A. 28
B. 19
C. 30
D. 32
I am not sure what to do. I am litterly so dumb at this stuff XD

you are asked to evaluate

x + 20 - 1

when x=9

so, replace x with 9!

9+20-1
= 29-1
= 28

not so hard, once you figure out what they have told you, and what they want.

1. C

2. D
3. A
4. B
5. C

your welcome :)

what are the rest of the answes

I forgot to change my name. Lol. Please help!

Thank you Steve!

THANKS STEVE

what's the answer

Thank you

No worries! Let's break it down step by step.

We have the following values: W = 13, x = 9, Y = 1.9, Z = 0.5.
The expression we need to evaluate is X + 20 - 1.

To find the value of X, we need to know its value in the given values. However, X is not given, so we cannot directly substitute a value for it.

Here's what we can do:
Step 1: Replace X with its given value.
Step 2: Perform the addition and subtraction operations in the expression.

Let's calculate it:

Step 1: Since X is not given, we cannot substitute a value for it. So, for now, we'll leave it as X.

Step 2: Substitute the given values and evaluate the expression:
X + 20 - 1
= 9 + 20 - 1 (Since X = 9)
= 29 - 1 (Performing the addition operation)
= 28 (Performing the subtraction operation)

So, the value of the expression X + 20 - 1, using the given values, is 28.

Therefore, the correct option is A. 28
