Answer: 1.8 x 103 meters
Step-by-step explanation:
The average of the two extremes is 1,700 meters. This would be 1.7x10^3 in scientific notation. None of the four options include this number. But three stand out as total losers. We can convert the answer options to see the difference:
O 1.7 x 102 meters = 170 meters [Loser]
O 1.8 x 103 meters = 1800 meters
O 1.7 x 10-3 meters = 0.0017 meters [Loser]
O 1.8 x 10-2 meters = 0.018 meters [Loser]
Answer: 2x+8=12, 5x+4=29
Step-by-step explanation:

Answer:
y = 10
Step-by-step explanation:
By definition, the internal angles of an equilateral triangle are all 60. So:
A = 5y + 10 = 60
5y + 10 = 60
5y + 10 - 10 = 60 - 10
5y = 50
5y/5 = 50/5
y = 10
Answer:
x=-11
because || means you just do the opposite
