Answer:
3. No errors were made. The problem was worked correctly.
Step-by-step explanation:
2(10x + 3) − x = 44
Distribute
20x +6 -x =44
Combine like terms
19x +6 = 44
Subtract 6 from each side
19x =38
Divide by 19
19x/19 =38/19
x =2
Answer: 9 goes into 63 7 times, but 9 does not go into

Answer:
The component form of the velocity of the airplane is .
Step-by-step explanation:
Let suppose that a bearing of 0 degrees corresponds with the direction and that angle is measured counterclockwise. Besides, we must know both the magnitude of velocity (), in miles per hour, and the direction of the airplane (), in sexagesimal degrees to construct the respective vector. The component form of the velocity of the airplane is equivalent to <u>a vector in rectangular form with physical units</u>, that is:
(1)
If we know that and , then the component form of the velocity of the airplane is:
The component form of the velocity of the airplane is .
