Answer:

5x + 7x + x = total number of songs

Step-by-step explanation:

x represents the number of pop tracks

since there are 5 times as many classical as there are pop then classical can be represented by 5x

since there are 7 times as many rap as there are pop then rap can be represented by 7x

when adding all these together you will find the total number of songs on the MP3

The answer to this equation​
12345 [234]

Answer:

x=3

Step-by-step explanation:

We are given the equation

log5x=log(2x+9)

This can be rewritten as

log5x-log(2x+9)=0

Now using the quotient rule for logarithms we can combine these two

log(\frac{5x}{2x+9} )=0

Next we can remove the log by using an inverse operation

10^{log(\frac{5x}{2x+9} )} =10^0\\\\\frac{5x}{2x+9}=1

Now we can solve for x

\frac{5x}{2x+9}=1\\\\5x=2x+9\\\\3x=9\\\\x=3
