Answer- D= 26° b= 5.48 d=2.57
Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)

Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km
