You gotta use trig take the incomplete data and extrapolate from it
\[\sum_{n=1}^{7} 2(-2)^{n-1}\]
Point L is the midpoint
The midpoint is halfway between the two points. In this case, Point F and Point B are 10 units away from each other. The midpoint is the distance between the points (10) divided by 2.
First, before multiplying to cancel the fraction, let's isolate x by subtracting both sides by 3:
b/9 < 1
To cancel out the fraction, we multiply both sides by 9:
x < 9
21/49 in simplist from would be 3/7.
Your answer is <em>3/7</em>
