JL = 70

Step-by-step explanation:

Since K is the midpoint of JL then JK = KL and

JL = JK + KL = 9x - 1 + 2x + 27 = 11x + 26

solve for x using JK = KL

9x - 1 = 2x + 27 ( subtract 2x from both sides )

7x - 1 = 27 ( add 1 to both sides )

7x = 28 ( divide both sides by 7 )

x = 4, hence

JL = 11x + 26 = (11 × 4 ) + 26 = 44 + 26 = 70

Mice21 [21]
Well you have no table for me to fill in but I can help you :)

Say that on the left side of your chart your x values are 1,2, and 3. 
just plug in those x values for x in the equation y=10x+1

so....
x        y
-----------
1      y=10(1)+1 = y = 11
------------
2       y = 10(2)+1 = y = 21
-------------
3       y = 10(3)+1 = y = 31

plz give me points :)
