Question

A surveyor is surveying a street. The surveyor is standing at point Plooking down the street at a No Parking sign at point A and a stop sign at point R. Given PA=3x-4, PR=21 meters, AR=7 meters and point A is between point Rand point What is the value of x in meters?​

Answer 1

Answer:

Step-by-step explanation:

If point A is between P and R, then;

PA+AR = PR

Given

PA=3x-4,

PR=21 meters,

AR=7 meters

Substitute

3x-4 +7 = 21

3x+3 = 21

3x = 21-3

3x =18

x =18/3

x = 6

Hence the value of x is 6m
