Answer:
4 songs
Step-by-step explanation:
Given data,
Adventure play sells mp3 = $18
Charges per song = $3.25
King music sell Mp3 = $23
Charges per song = $2
Let number of songs be Y, then we can calculate by using following method,
Adventure play MP3 cost + charges per song = Kings Music MP3 cost + charges per song
By putting the value, we get
$18 + $3.25 Y = $23 + $2 Y
By solving the equation,
$3.25 Y - $2Y = $23 - $18
$1.25 Y = $5
Y = $5 ÷ $1.25
Y = 4 songs
Hence, for 4 songs the cost be same.
Answer:
(3/7)^7
Step-by-step explanation:
When multiplying exponents we can use the formula: a^m x a^n = a^m+n.
In this case, we can plug in 3/7 for a, and their respective exponents as m and n.
(3/7)^3 x (3/7)^4= (3/7)^3+4= (3/7)^7

The first equation is 
(Equation 1)
The second equation is
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,


by simplifying the given equation,


Using discriminant formula,


Now the formula for solution 'x' of quadratic equation is given by:


Hence, these are the required solutions.
