The symphonic choir and the jazz choir are recording songs for an album. The album can be no more than 72
minutes long. The jazz choir records 7 songs with an average of 3 minutes per song. Each symphonic choir song is
an average of 3.5 minutes long. What is the maximum number of songs the symphonic choir can record?

The maximum number of songs that the symphonic choir can record is 14

Step-by-step explanation:

Let

x ----> the number of songs of the symphonic choir

we know that

The number of songs of the jazz choir multiplied by its average time per song plus the the number of songs of the symphonic choir multiplied by its average time per song, must be less than or equal to 72 minutes

so

The inequality that represent this situation is

solve for x

subtract 21 both sides

divide by 3.6 both sides

therefore

The maximum number of songs that the symphonic choir can record is 14

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
