Just number 23 super confused
vodka [1.7K]

Answer:

x = -7

Step-by-step explanation:

This is an exponential equation.

\frac{1}{2}^x=128

We need to take log(or ln) of both sides and use logarithm property to solve this.

So, let's take ln of both sides, so we have:

ln(\frac{1}{2}^x)=ln(128)

Now, we will use this property shown below to further simplify:

ln(a^b)=bln(a)

So, we now have:

ln(\frac{1}{2}^x)=ln(128)\\xln(\frac{1}{2})=ln(128)\\x=\frac{ln(128)}{ln(\frac{1}{2})}\\x=-7

The value of x is -7

A man sells a sofa for rs 3210 making a profit of 7% what would have been his profit percent if he had sold it for rs 3360?
Digiron [165]
Let x be the original cost for the sofa.
X x (1 + 0.07) =3210
X = 3000
Now we know the cost for the sofa.
Let p be the profit percent.
3000 x (1 + p) = 3360
P = 0.12
So the percentage profit is 12%
