X=-1 (negative one)
(i need this part to post the answer so just ignore it lol)
Now, she writes 4 notes every 1 hour.
so in 2 hours she has written 8 notes, and the remaining is 50 - 8 or 42.
in 3 hours has written 12 notes, and remaining are 50 - 12, or 38, and so on.
now, how many hours will it take her to them all? or, how many times does 4 go into 50? 50 /4 or 12.5.
so it will take her 12 hours and a half to do them all, at that time, the remaining notes are 0, because she's done, and the hours are 12 and a half.
Answer:
The value of x = 14 ...
The value of ∠AED = ( 7x + 15) = 7(14) + 15 = 113
The value of ∠AEB = 5x-3 = 5(14) -3 = 67
Step-by-step explanation:
=> ∠BEC = ∠AED { vertically opposite angles }
∠AED = (7x + 15)°
=> ∠AEB + ∠BEC = 180° { linear pair }
=> ( 5x-3) + ( 7x+15) = 180°
=> 5x -3 + 7x + 15 = 180°
=> 12x + 12 = 180°
=> 12( x +1 ) = 180°
=> x+1 = 180/12
=> x +1 = 15
=> x = 15-1
=> x = 14
We need to find 82.5% of 40 men (the total on the team.). The 200 lbs is extra information that we do not need to use in our calculation - so ignore that.
To find 82.5 percent - move the decimal two places to the left (.825) and multiply by 40.
40 x .825 = 33. 33 men are over 200 lbs on the team.
