I have 4 questions 1. Suppose point T is between points R and V on a line. If RT = 63 units and RV = 131 units, then what is TV? 131 194 68 80 2.Given point P is between M and N. If MN = 26, MP = x + 4, and PN = 2x + 1, what is the value of x? x = 3 x = 7 x = 12.5 x = 22 3.Given M is the midpoint of HJ, HM = 4x - 12, and MJ = 3x + 9. What is the value of x? 4.If D is the midpoint of CE, DE = 2x + 4, and CE = 6x + 2, then what is CD?
