Where are the graphs to match the inequalities with?
Answer: 161 packages of gift wrap and the 44 packages of greeting cards
Step-by-step explanation:
We are told the class sells 205 packages in total of gift wraps and greting cards:
(1)
Where 
is the number of packages of gift wrap and 
is the number of packages of greeting cards.
In addition, we are told the class receives a total of 
selling each package of gift wrap for 
and each package of greeting cards for 
:
(2)
Isolating from (1):
(3)
Substituting (3) in (2):
(4)
Finding :
(5) This is the number of packages of greeting cards
Substituting (5) in (1):
(6)
Isolating :
This is the number of packages of gift wrap
The unit ton, or metric ton, is a non-SI unit but commonly used in the United States. It is both approved by the NIST and the U.S National Institute of Standards and Technology. The equivalence is, 1 metric ton is equal to 1,000 kilograms. So, a metric ton is a thousand times bigger than a kilogram.
The sum of interior angles of this pentagon is 540 ( 180(5-2)=540)
So it is : 85+120+90+2x-10+180-x=540. ( in case you ask where did I get 180-x , it is bc the line is 180 degree so minus x it will help us find one of the interior angles)
So x+465=540. x=75
The value of exterior is 75
