Question

s is the mid - point of rt. if st = 7x and rt = 8x + 6, what is rt? simplify your answer and write it as a proper fraction, mixed number, or integer.

Explanation:

Step1: Use mid - point property

Since \(S\) is the mid - point of \(\overline{RT}\), then \(RS = ST\) and \(RT=RS + ST = 2ST\). Also, \(RT = 8x+6\) and \(ST = 7x\), so \(8x + 6=2\times7x\).

Step2: Solve the equation for \(x\)

Step3: Find the value of \(RT\)

Substitute \(x = 1\) into the expression for \(RT\). Since \(RT=8x + 6\), then \(RT=8\times1+6=14\).

Answer:
