=42 -   \frac{315}{50}

= 42 - 6 \:  \frac{15}{50}

= 41 \:  \frac{50}{50}  - 6 \:  \frac{15}{50}

If k is the midpoint of JL, JK =8x + 11 and KL =14x-1, find JL
katen-ka-za [31]
J------------K------------L
   8x+11        14x-1


<span>If K is the midpoint of JL then JK = KL
8x+11 = 14x-1
11 + 1 = 14x - 8x
12 = 6x
x = 12/6
x = 2

JK = 8x + 11 = 8*2 + 11 = 16+11 = 27
KL = JK = 27

JL = JK + KL = 27 + 27 = 54</span>
