The amount of time Jill spent to do her homework 
= 9 1/2 hours. which equals to  570 minutes.

Which means, the amount of times Jack needed to do his is 
= 570 minutes x 1.5
= 855 minutes which equals to 14 1/4 hours

Why are (1,2) and(2,1) not equal ordered pair? ​
vladimir1956 [14]

Answer:

The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.

Step-by-step explanation:

The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.

Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).

Hope I helped!

Best regards!!
