Answer:

JM = 10

Step-by-step explanation:

Because MN║JL,

$\frac{MK}{JM} = \frac{KN}{NL}$

$\frac{5}{2x + 4} = \frac{6}{12}$ = $\frac{1}{2}$

2(5) = 1(2x + 4)

10 = 2x + 4

2x = 6

x = 3

JM = 2x + 4 = 2(3) + 4 = 6 + 4 = 10

2.5 = 2 5/10 as a Mixed fraction

To get a improper fraction, multiply the whole number with the denominator, and then add the numerator to the answer, giving the numerator (keep the denominator number)

2 x 10 = 20
20 + 5 = 25

25/10 is your answer
