Answer:

a = -40/3

7a = 4a - 40

7a - 4a = - 40

The snowboarder went off a jump and did a 180. In which direction was the snowboard facing when he landed? How do you know?
dem82 [27]

Answer:

The snowboard was facing the opposite direction from which it started the jump.

Step-by-step explanation:

You may not have learned this yet, but a 360 degree turn makes a complete rotation. Knowing this, 180 is half of 360. This means that the snowboard made a half-way turn. Therefore, it is facing the opposite direction.
