Answer:

$\frac{3}{5}x+2=\frac{2}{3}x\\\\\frac{3}{5}x+2-2=\frac{2}{3}x-2\\\\\frac{3}{5}x=\frac{2}{3}x-2\\\\\frac{3}{5}x-\frac{2}{3}x=\frac{2}{3}x-2-\frac{2}{3}x\\\\-\frac{1}{15}x=-2\\\\\left(-\frac{1}{15}x\right)\left(-15\right)=\left(-2\right)\left(-15\right)\\\\x=30$

hope this helps you

The term can also be written as:

Musya8 [376]

The correct expansion is the one in option b:

$Log_9(\frac{6}{11}) = Log_9(6) - Log_9(11)$

<h3>How to rewrite the term?</h3>

Here we must use the logarithmic property:

$Log(a) -Log(b) = Log(\frac{a}{b})$

Our expression in this case is:

$Log_9(\frac{6}{11})$

Using the above property, we can rewrite the expression as:

$Log_9(\frac{6}{11}) = Log_9(6) - Log_9(11)$

From this, we conclude that the correct option is B.

Im supposed to solve this equation using logarithms but I don't know how.

Ghella [55]

Given:

$3(4^x)=5^(x+1)$

To find:

The solution of the given equation.

Solution:

We have,

$3(4^x)=5^(x+1)$

It can be written as

$3((2^2)^x)=5^(x+1)$

$3((2^{2x})=5^(x+1)$ $[\because (a^m)^n=a^{mn}]$

Taking log on both sides.

$\log [3((2^{2x})]=\log 5^(x+1)$

$\log 3+ \log ((2^{2x})=\log 5^(x+1)$ $[\because \log (ab)=\log a+\log b]$

$\log 3+ 2x\log 2=(x+1)\log 5$ $[\because \log x^n=n\log x]$

Putting values of logarithms, we get

$0.477+ 2x(0.301)=(x+1)0.699$ $[\because \log 2 =0.301, \log 3=0.477, \log 5=0.699]$

$0.477+ 0.602x=0.699x+0.699$

$0.602x-0.699x=0.699-0.477$

$-0.097x=0.222$

Divide both sides by -0.097.

$x=\dfrac{0.222}{-0.097}$

$x=-2.288656$

$x\approx -2.289$

Therefore, the value of x is -2.289.
