Carmen made 270$ for 18 hours of work. At the same rate, how many hours would she have to work to make 165$?

11 hours

Step-by-step explanation:

270/18=15 per hour

so 165/15 = 11

11 hours

Step-by-step explanation:

270:18 simplified is 15:1

165/15 = 11

Hope this helps!

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
