Answer:

Step-by-step explanation:

m∠AOC = 180 as it is straight line

m∠AOC = m∠AOB + m∠BOC

m∠AOB + m∠BOC = 180

3x + 124 + 6x + 29 = 180

9x + 153 = 180

9x = 180 - 153

9x = 27

x = 27/9

x = 3

m∠BOC = 6x +29 = 6*3 + 29 = 18 +29 = 47

USPshnik [31]

Answer:

Step-by-step explanation:

1) y = 50x + 2500

2) y = 200x + 1000

if we build a system with the two equations, we have:

50x+2500 = 200x + 1000

150x = 1500

x = 10

y = 2000 + 1000 = 3000

3) 10

4) $3000
