7. Jorge wants to ride his bicycle 31 miles this week. He has already ridden 13 miles. If he rides for 3 more days, write and solve an equation which can be used to determine m, the average
number of miles he would have to ride each day to meet his goal.

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

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

by good luck mark me as brainliest

have a nice day

lockers 1, 4, 9, 16, 25, 40, and 49 are open
