1. tabitha was shooting free throws in gym class. she completed 8 of the shots, which was half of 4 more than joan completed. what is the number of free throws, n, that joan completed?

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

range is infinite on both x and y axis positive and negative

step-by-step explanation:

the answer is 13/48

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
