Answer: one real solution
Step-by-step explanation:
11- \frac{1}{2} y=3+6x
Taking y to the other side;
11-3-6x= \frac{1}{2} y
8-6x= \frac{1}{2}y
Multiply each side by 2
16-12x=y
y=16-12x
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph
Ok this is the answer to this question 2(x+1)
