We take the numbers, add them together, then divide by the how many numbers there are:
(34 + 68) / 2
(102) / 2
51
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>
Answer:
50
Step-by-step explanation:
8 x 4 + 9 -9 + 18
PEMDAS says multiply first
