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:
-9
Step-by-step explanation:
4x-12=8x+24
we change the signs when we bring 8x on the left hand side so positive 8x becomes -8x.
4x-8x-12=24
we change sign when we bring -12 on the right hand side it becomes +12
4x-8x=24+12
-4x=36
x=36/-4
x=-4
Answer:
20 + 2 =22 or in words it would be twenty two
Step-by-step explanation:
-4(x+3) -12x + 5
-4x -12- 12x + 5 (Distributed)
-16x - 7 ( Combine like terms)
Answer-16x - 7.
Answer: 1 1/3
Step-by-step explanation:
-4 + 5 = 1
-1/3 + 2/3 = 1/3
OR
Turn them both into mixed numbers: -13/3 + 17/3
-13/3 + 17/3 = 4/3 = 1 1/3
