Answer:

EF = 58

Step-by-step explanation:

Starting with the premise that

DF = DE + EF, then

9x - 39 = 47 + 3x + 10 ( subtract 3x from both sides )

6x - 39 = 57 ( add 39 to both sides )

6x = 96 ( divide both sides by 6 )

x = 16

Hence

EF = 3x + 10 = (3 × 16) + 10 = 48 + 10 = 58

EastWind [94]
P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
