The hardcover version of a book weighs twice as much as its paperback version. the hardcover book and the paperback together weigh 4.2 pounds. which system of equations can be used to find h, the weight of the hardcover book, and p, the weight of the paperback?
a) h = p − 4.2
h = 2p
b) h = 4.2 − p
p = 2h
c) h = p − 4.2
p = 2h
d) h = 4.2 − p
h = 2p

Option D is correct.

System of equations can be used is given by:

Step-by-step explanation:

here, h represents the weight of the hardcover book, and p represents the weight of the paperback.

As per the given statement: The hardcover version of a book weighs twice as much as its paperback version.

⇒

Also, it is given that the hardcover book and the paperback together weigh 4.2 pounds

⇒

or

Therefore, the system of equations can be used is given by:

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
