Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat how long does myron need to cook 3 kilograms of meat

7.2 hours

Step-by-step explanation:

Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat

12 hours to cook 5 kilograms of meet

we need to find the number of hours needs to cook 3 kilograms

Let x be the number of hours to cook 3 kilograms

Make a proportion

solve for x

cross multiply it

Divide both sides by 5

so x= 7.2 hours

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

20
