Rewrite the equation for x, and express its value in terms of a. 3/ax-4=20

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

By clearing "x" we have:

Adding 4 to both sides of the equation:

Multiplying by on both sides of the equation:

So,

b is the final answer! : )

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
