Answer:
10
Step-by-step explanation:
If J is between H and K then HJ + JK = HK
Given
HJ=6x-5
JK=4x-6
KH=129
Required
The value of x
Substituting the given parametrs into the formula;
6x-5+4x-6 = 129
6x+4x-5-6 = 29
10x-11 = 129
add 11 to both sides
10x-11+11 = 129+11
10x = 140
divide both sides by 10
10x/10 = 140/10
x = 10
Hence the value of x is 10
