13 - 0.75w + 8x when w = 12 and x = 1/2

The answer is 8.

Step-by-step explanation:

When it comes to equations like these, all you have to do is substitute the values to the corresponding variables. In other words:

13 - 0.75(12) + 8(1/2)

13 - 9 + 4

8

13 - 0.75w + 8x when w = 12 and x = 1/2 = 8

Step-by-step explanation:

As per the given equation that is thirteen minus zero point seven five 'w' plus eight 'x'. The given in the question is 'w' that is twelve and 'x' that is also twelve. Placing the values into the equation which is thirteen minus zero point seven five multiple by twelve plus eight multiple by twelve. Simplifying it further gives us the answer that is eight.

Numeric calculation is as following;

13 - 0.75w + 8x

if w = 12 and x = 1/2

13 - 0.75 (12) + 8 (1/2)

= 13 - 9 + 4 = 4 + 4

= 8
