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

gayaneshka [121]

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

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

$\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}$

As with the last question, change the sign to multiplication and "flip" the second term:

$\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}$

Multiply straight across:

$=\frac{(2x-1)(x+1)}{(x+1)(3x)}$

Cancel the (x+1) term:

$=\frac{2x-1}{3x}$

Cannot be simplified further.

Solve for x. <img src="https://tex.z-dn.net/?f=15log_%7B8%7D%20%28-2x-7%29-2%3D3" id="TexFormula1" title="15log_{8} (-2x

vova2212 [387]

Answer: $x=-4.5$

Step-by-step explanation:

Add 2 to both sides of the equation and divide both sides of the equation by 15. Then:

$15log_{8} (-2x-7)-2+2=3+2\\15log_{8} (-2x-7)=5\\\\\frac{15log_{8} (-2x-7)}{15}=\frac{5}{15}\\\\log_{8}(-2x-7)=\frac{1}{3}$

Apply base 8 to both sides of the equation:

$8^{log_{8}(-2x-7)}=8^{\frac{1}{3}}\\\\-2x-7=8^{\frac{1}{3}}$

Solve for "x", then you get:

$-2x-7=8^{\frac{1}{3}}\\\\-2x=\sqrt[3]{8}+7\\\\ x=\frac{\sqrt[3]{8}+7}{-2}\\\\x=-4.5$
