Judah worked at a bakery for 14 hours last week. He spent $12 of his earnings on a cake for his father's birthday. If he was left with $86 after buying the cake, what is Judah's hourly wage.

$7 per hour

Step-by-step explanation:

86+12=98

98/14=7

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

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
