Answer:

Option (E)

Step-by-step explanation:

$\frac{a}{b}=\frac{c}{d}=k$

$\frac{a}{b}=k$

$b=\frac{a}{k}$ ------(1)

$\frac{c}{d}=k$

$d=\frac{c}{k}$ -------(2)

Since, $\frac{6a+24}{md+6b}=k$

By substituting the values of b and d from equation (1) and (2),

$\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k$

$\frac{k(6a+24)}{6a+mc}=k$

$\frac{6a+24}{6a+mc}=1$

6a + 24 = 6a + mc

mc = 24

m = $\frac{24}{c}$

Therefore, Option (E) will be the correct option.

Which equations are equivalent to log 4x=3

Lady bird [3.3K]

I'm not sure that this is what you wanted, but the solution is x = 2500
$log(4x) = 3 \\ rule > \: log_{a}(b) = x < = > \: b = {a}^{x} \\ 4x = {10}^{3} \\ 4x = 10 \: 000 \\ x = \frac{10 \: 000}{4} \\ x = 2500$
Note: when we have no number as the logarithmic base, it is 10 by default.

Solve for x, x^2-3x-5=0

Sophie [7]

Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.
