If <span>EC </span>bisects ∠BED, then m∠BEC = m∠DEC
11x + 2 = 8x + 20
11x - 8x = 20 - 2
3x = 18
x = 6
m∠BED = 2 * m∠BEC
= 2(11x + 2)
= 2(11*6 + 2)
= 2(66 + 2)
= 2 * 68
= 136°
Answer:
Step-by-step explanation:
First, write an equation. 55x+40=190.
X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The +40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.
55x+40=190
55x=150
x=2.72727272...
So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
Answer:
x=52
Step-by-step explanation:
Original Equation: (3x-6)+(2x-8)+(x+10)+(x)=360
Combine Like Terms: 7x-4=360
Distribute: 7x=356
Simplify: x=52
