write fractions for each type of song out of the total
10/45 country
15/45 pop
5/45 r&b
10/45 rap
5/45 techno
write these fractions in their simplest forms
2/9 country
1/3 pop
1/9 r&b
2/9 rap
1/9 techno
<em>the chances of the next song played on shuffle being pop is 15/45, or 1/3</em>

First, let's review the formula for the "sum of two cubes:"
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).
Thus,
9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)
Answer:
Step-by-step explanation:
A) When the first equation is multiplied by 5 and the second equation by –6 ,
the equations become,
35x + 60y=54
-30x - 60y=60
Hence we can eliminate y by adding the equation.
B) When the first equation is multiplied by -5 and the second equation by 6 ,
the equations become,
-35x - 60y=54
30x + 60y=60
Hence we can eliminate y by adding the equation.
C) When the first equation is multiplied by -5 and the second equation by 7,
the equations become,
-35x - 60y=54
35x - 70y=60
Hence we can eliminate x by adding the equation.
D) When the first equation is multiplied by 5 and the second equation by -7,
the equations become,
35x + 60y=54
-35x - 70y=60
Hence we can eliminate x by adding the equation.
E) When the first equation is multiplied by -5 and the second equation by 10,
the equations become,
-35x - 60y=54
50x - 100y=60
Hence we can not eliminate x by adding the equation.
The answer is x = 15
The equation would be x + 2 = 17
14(9•x) X would be the variable, aka the number.
