If triangle ABC is equilateral, you know that each angle is 60 degrees because 180(the total of all angles in a triangle) divided by 3 is 60. 60 would equal 3x-12. 60=3x-12 then you cancel out the 12, 56=3x, and finally divide by 3... x=18.66! Hope this helps!

b is the answer
<u><em>Answer:</em></u>
a. The point (4,9) appears in both tables
<u><em>Explanation:</em></u>
<u>Note:</u> This question can be solved without the need of the tables
<u>A solution of a system of equations</u> is defined as a point (or set of points) that satisfy both equations
<u>This means that,</u> this point should belong to all the equations in the system
Now, a table is used to show a set of points that belong to a certain line
This means that, all vales in the table belong to the line they represent
<u>Since the point (4,9) appears in both tables</u>, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines
Hope this helps :)
Answer:
$0.85
Step-by-step explanation:
2 juice pouches- $2.50
3c+2.50=5.05 (c is for bags of chips)
3c=5.05-2.50
3c=2.55
c= $0.85
So one bag of chip is $0.85
The range of widths is {1.23,1.31} so none will be rejected, answer A.
