Question

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

(need help! fast! TmT)

Answer 1

8

Explanation:

Given expression is

`13-0.75w\:+\:8x`

and we are asked to evaluate this expression when

`w = 12 ,\: x = (1)/(2)`

`0.75w = 0.75 * 12 = 9`

`8x = \8 * (1)/(2) = 4`

`\text{So the expression at $w = 12 \; , x= (1)/(2)$ evaluates to}`

13 - 9 + 4 = 8

Answer: 8

Answer 2

Answer: To evaluate 13 - 0.75w + 8x when w = 12 and x = 1/2, we substitute these values into the expression:

13 - 0.75w + 8x = 13 - 0.75(12) + 8(1/2)

Simplifying the expression inside the parentheses first:

13 - 9 + 4 = 8

Substituting this value into the expression:

13 - 0.75w + 8x = 13 - 0.75(12) + 8(1/2) = 13 - 9 + 4 = 8 + 4 = 12

Therefore, the value of 13 - 0.75w + 8x when w = 12 and x = 1/2 is 12.
