Solve the equation. Round to the nearest hundredth. Show work.

Burka [1]

Answer:

$x=-0.75$

Step-by-step explanation:

The given equation is

$4^{-5x-7}=6^{2x-1}$

We take logarithm of both sides to base 10.

$\log(4^{-5x-7})=\log(6^{2x-1})$

$(-5x-7)\log(4)=(2x-1)\log(6)$

We expand the brackets to get;

$-5x\log(4)-7\log(4)=2x\log(6)-\log(6)$

Group similar terms;

$-7\log(4)+\log(6)=2x\log(6)+5x\log(4)$

$-7\log(4)+\log(6)=(2\log(6)+5\log(4))x$

$\frac{-7\log(4)+\log(6)}{(2\log(6)+5\log(4))}=x$

$x=-0.752478$

To the nearest hundredth.

$x=-0.75$

the ratio of rock music to total CDs that Ella own is 25/40 polo has 50 rock music CDs the ratio of rock music to total CDs in h

cluponka [151]

If Polo has $n$ CDs, then $\frac{50}n=\frac{25}{40}$ hence $n=\frac{50\cdot40}{25}=80$

Hence, they have a total of $80+40=\boxed{120\text{ CDs}}$
