First set up the equation (sum of the angles is 180)
2x + 2(x-1) + (5x +2) = 180
distribute:
2x + 2x -2 + 5x +2 = 180
combine like terms:
9x = 180
solve for x:
x = 20
SO:
2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees
check: 40 + 38 + 102 = 180
The exponent tells you how many places to move.
The worm would move 6.375 inches in 85 minutes (1 hour 25 minutes).
Answer:
The answer is D: 37%
Ignore this answer its wrong, I think. Yeah you're gonna need someone else to figure this out. How do you delete answers on here?
