To determine if adding \(7 + 2\) and then dividing by \(2\) helps find the midpoint of line segment \(JK\), we need to consider what \(7\) and \(2\) represent.
If \(7\) and \(2\) are the \(x\)-coordinates of points \(J\) and \(K\), then the calculation \((7 + 2) \div 2\) finds the average of these \(x\)-coordinates, which gives the \(x\)-coordinate of the midpoint.
Similarly, if \(7\) and \(2\) are the \(y\)-coordinates of points \(J\) and \(K\), the calculation can be used to find the \(y\)-coordinate of the midpoint.
Given the responses provided, the best answer that matches this reasoning is:
Yes because (7+2)÷2 calculates the average, or midpoint, of the x-coordinates of points J and K.
If \(7\) and \(2\) represent the \(x\)-coordinates, this correctly describes the use of the average to find the midpoint.
