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
Answer:
Susan worked for 10 mins
Step-by-step explanation:
because twice as fast 20 mins and 10 plus equal 30 I MIGHT BE WRONG
Let x denote the length of the longer first piece and y the length of the shorter piece.
We have x+y=10 and x=3y-2 hence 3y-2+y=10 => 4y=12 => y=3 => x=7
The shorter piece is 3 feet long
The answer is true.
Really all you ever need is two points and you should find an equation.
