If the triangle is an equilateral triangle the angles should be all 60 as (60+60+60=180) if that’s true then a congruent line from the triangle would form a 60 degree angle.
so x=60°
To answer this you will use the formula for finding area of a parallelogram.
A = bh
3 inches x 2 inches
A = 6 square inches per piece of paper
6 square inches x 15 = 90 square inches
90 in.² of paper is used to make 15 pieces.
820.681 in expanded form would look like this:
The answer to your question would be 6.25 and the equation you need to solve is: (0.8x+2)/0.01=700.
Hope this helps!
Answer: Sam = $225 George = $300
<u>Step-by-step explanation:</u>
NOTES:
Sam: s
George: g = s + 75
Together: s + g = 525
a.
The two equations that can be created are "George" and Together"
The system is: 
b.
see attached graph
c.
The intersection of the two lines is at (225, 300). Since Sam represented the x-axis and Georege represented the y-axis, then Sam = $225 and George = $300.
BONUS:
This system can also be solved algebraically using the substitution method.
Replace "g" with "s + 75" into the second equation:
s + (s + 75) = 525
2s + 75 = 525
2s = 450
s = 225
Next, input the s-value into the George equation to solve for g:
g = s + 75 = (225) + 75 = 300
