Kelly has 4 times as many songs as lou. tiffany has 6 times as many songs as lou. together they have 682 songs. how many songs does kelly have?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
