 Rewriting the expression we have:
 (ab) ^ - 2 = 1 / (ab) ^ 2
 Then, for power properties we have:
 1 / (ab) ^ 2 = 1 / (a ^ 2b ^ 2)

A 3 pound pork loin can be cut into 10 pork chops with equal weight. How many ounces is each pork chop?
Misha Larkins [42]

Answer

Find out the how many ounces is each pork chop .

To prove

Relationship between pound and ounce .

1 pound = 16 ounce

As given

A 3 pound pork loin can be cut into 10 pork chops with equal weight.

Now for 3 pound pork loin = 3 × 16

                                            = 48 ounces

now 48 ounces of  pork loin can be cut into 10 pork chops with equal weight.

Than

weight\ of\ each\ pork\ chops = \frac{48}{10}

                                                         = 4.8 ounces

Therefore the weight of each ounce be 4.8 ounces .

Use substitution to determine if the solution is correct (PINK HIGHLIGHTED ONE!!!)
mart [117]

Answer:

It is not correct.

Step-by-step explanation:

If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.

Hope this is helpful! :)
