Step-by-step explanation:
the international telecomination union (ITU) defined the third generation (3g) of mobil telephony standards IMT_2000 to facilitate growth, increase bandwidth and support more diverse applications.for example gsm could deliver not only voice but also circuit switched data at speeds up to 14.4kbps.
For this case, the first thing to do is define a variable.
We have then:
- <em>x: the monetary value of that 120 square foot piece of plastic wrap
</em>
We write now the proportion that models the problem.
We have then:

From here, we clear the value of x.
We have then:

Calculating we have:

Answer:
the monetary value of that 120 square foot piece of plastic wrap is:

Answer:
Answer of 4 is 5 and answer of 5 is -1
7x-5<13x-3
Minus 7x
-5<6x-3
then add 3
-2<6x
Then divide -2 by 6 and 6x by 6
-1/3>x
I think thats right
