Answer: x = 7
Step-by-step explanation:
do opposites to both sides. what is the opposite of -5? it would be plus 5.
add 5 to both sides
3x = 21
now what is the opposite of 3 times x? 3 divided by.
divide 3 to both sides
x = 7
189000/x=100/4.5
<span>(189000/x)*x=(100/4.5)*x</span>
<span>189000/22.2222=x </span>
<span>8505=x </span>
Answer:
Velocity of plane is 100 mi/hr along northeast direction
Step-by-step explanation:
From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction
since the velocity of wind and plane is exactly opposite
⇒ relative velocity of plane with respect to wind is given by
where is the velocity of plane = 150mi/hr and = velocity of wind = 50 mi/hr
Therefore, = alond northwest direction
Therefore, velocity of plane is 100 mi/hr along northeast direction
