We know: the sum of measures of triangle angles is 180°.
Therefore we have the equation

Substitute
:

<h3>Answer: 180 - 7x</h3>
7/12 because it would come out to be 21/36, and the simplified version of that is 7/12<span />
Distribute
-2(x+6)+3
-2x-12+3
-2x-12+3=-11x+4(x+4)
Distribute
4(x+4)
4x+16
-2x-12+3=-11x+4x+16
Combine Numbers && Variables
-2x-9=-7x+16
Add The 7 Over To The -2x
5x-9=16
Add 9 Over To 16
5x=25
x=5
So 5 Is Your Answer

The answer will be $13.72 for 7 bags of popcorn.
to find this answer, you first take 5.88 and divide it by 3 to find out how much one bag costs.
the answer to 5.88/3 is 1.96, so you multiply 1.96 by 7 to get the answer of how much 7 bags of popcorn will cost.
hope this helps!
