Answer:

B. 112°

Step-by-step explanation:

4x -4 = (3x+4) + (2x-44)

4x -4 = 5x - 40

5x - 4x = -4 + 40

x = 36

∠BCA = 3 * 36 + 4 = 112

Solve for W. 4w-4+2(5w+8)=-2(w+3) Simplify your answer as much as possible.

Answer:

w = $-\frac{9}{8}$

Step-by-step explanation:

The question is $4w-4+2(5w+8)=-2(w+3)$

We can first use distributive property to simplify, the distributive property is $a(b+c)=ab+ac$

Thus we have:

$4w-4+2(5w+8)=-2(w+3)\\4w-4+10w+16=-2w-6$

Now we combine like terms and simplify to get the final answer for w.

$4w-4+10w+16=-2w-6\\14w+12=-2w-6\\14w+2w=-6-12\\16w=-18\\w=\frac{-18}{16}\\w=-\frac{9}{8}$

Thus, w = $-\frac{9}{8}$
