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

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
