Answer:
Yes! See explanation below!
Step-by-step explanation:
If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.
Ex:

Answer:
42:49
Step-by-step explanation:
6x + 7x = 91
13x = 91
x = 7
6 x 7 = 42
7 x 7 = 49
then 42:49
Answer:
1.6
Step-by-step explanation
You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.
After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)
you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6
Answer:
Yes, the average speed for the entire trip from A to C is equal to 
Step-by-step explanation:
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:

If the beginning and ending velocities for the motion are known, and the acceleration is constant, the average velocity can also be expressed as:

We Know that:

Replacing the values:

2 * 4/3= 8/3
3/4 * 2/1= 6/4= 3/2
3/2*8/3= 24/6= 4
