question
what is the value of the expression below when w = 7 and x = 4?
10w - 9x

Explanation:

Step1: Substitute w and x values

Substitute \( w = 7 \) and \( x = 4 \) into \( 10w - 9x \), we get \( 10\times7 - 9\times4 \).

Step2: Calculate each term

Calculate \( 10\times7 = 70 \) and \( 9\times4 = 36 \).

Step3: Subtract the two results

Subtract: \( 70 - 36 = 34 \).

Answer:

34
