Jose asks his friends to guess the higher of two grades he received on his math tests. he gives them two hints. the difference of the two grades is 16. the sum of one-eighth of the higher grade and one-half of the lower grade is 52. the system that represents his scores is below.

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

the anwser is d) 75°
