Jack's brother is 14 years older than him. In six years 'time, Jack's brother will be twice as old as him. How old is Jack now?

8

Step-by-step explanation:

Jacks age: x-14

Jack's brothers age: x

In 6 years time:

Jack's age: x-8

Jack's brother's age: x + 6

Given that:

x+6 = 2(x-8)

Simplify:

x+6 = 2x-16

x+22 = 2x

2x = x+22

x = 22

we mentioned earlier that Jack's brother's age was x. but Jack's age was x-14.

So, Jack's age: 22-14 = 8

Hope this helps.

Good Luck

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
