Barney has 103 model cars. Ryan has 2 times as many model cars. How many model cars does Ryan have?

Ryan has 206 model cars.

Step-by-step explanation:

This can be represented in the equations below, where b is amount of cars Barney has and R is amount of cars Ryan has.

If we insert b (which is 103) in for b in the second equation, you'd find the answer.

There is the answer

1

step-by-step explanation:

it's the only multiple of both and the least

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
