Question

Evalúa 13-0{,}75w+8x13−0,75w+8x13, minus, 0, comma, 75, w, plus, 8, x cuando w=12w=12w, equals, 12 y x=\dfrac12x= 2 1 ​ x, equals, start fraction, 1, divided by, 2, end fraction.

Answer 1

`13- 0.75 * (12) + 8 * ((1)/(2) ) = 13-9+4\\\\13-5=8`

Therefore, the result after evaluating the expression is:

8

Explanation:

Evaluate 13-0.75w+8x13−0.75w+8x13, minus, 0, point, 75, w, plus, 8, x when w=12w=12w, equals, 12 and x=\dfrac12x= 2 1 ​ x, equals, start fraction, 1, divided by, 2, end fraction.

For this case we have the following expression:

`13-0.75w + 8x`

Evaluate for the following values:

w = 12

x = 1/2

We Substituting the values we have:

`13- 0.75 * (12) + 8 * ((1)/(2) ) = 13-9+4\\\\13-5=8`

Therefore, the result after evaluating the expression is:

8
