Answer:
(13, 10 )
Step-by-step explanation:
Given the 2 equations
x = y + 3 → (1)
x + 7 = 2y → (2)
Substitute x = y + 3 into (2)
y + 3 + 7 = 2y
y + 10 = 2y ( subtract y from both sides )
10 = y
Substitute y = 10 into (1) for corresponding value of x
x = 10 + 3 = 13
solution is (13, 10 )
First simplify 3x + 12 - 6x to -3x - 12
Next subtract 12 from both sides
Next subtract -9 - 12 and that would be -21
Next divide both sides by -3
Next lets simplify the fraction -21/-3 into 21/3 since those two negatives make a positive.
Lastly simplify the fraction 21/3 to get the answer.
Answer: x ≥ 7
<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
2,160 = (sides -2) * 180
2,160 / 180 = sides -2
12 = sides -2
sides = 14
