Final answer:
The value of the expression 8w - 5x is 22 when w is 4 and x is 2.
Step-by-step explanation:
To find the value of the expression 8w - 5x when w is 4 and x is 2, we simply substitute these values into the expression.
- First, substitute w = 4 into the expression: 8 × 4 = 32.
- Next, substitute x = 2 into the expression: 5 × 2 = 10.
- Then, subtract the second result from the first: 32 - 10 = 22.
So, the value of the expression 8w - 5x when w = 4 and x = 2 is 22.
