First, distribute the 7:

7w + 14 + 0.5w = 5

Combine like terms:

7.5w + 14 = 5

7.5w = -9

Divide both sides by 7.5 to solve for w:

w = -9/7.5 = -1.2

The answer is -1.2

- Which of the following is the correct distance between the points (-5, 3) and (7,8)?

JulsSmile [24]

Answer:

13 units

Step-by-step explanation:

(x₁,y₁) = (-5 , 3) & (x₂ , y₂) = (7 ,8)

$Distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}} \\$

$= \sqrt{(7-[-5])^{2}+(8-3)^{2}} \\\\= \sqrt{(7+5)^{2}+(8-3)^{2}} \\\\= \sqrt{(12)^{2}+(5)^{2}}\\\\=\sqrt{144+25}\\\\=\sqrt{169}\\\\= 13$
