Answer:

A.8 ; B.32 ; C. 13 ; D. 5 ; E. X=±3

Step-by-step explanation:

A. X/12 =2/3

X =(2 X 12) /3

X =8

 

B. 6/8 = 24/X

8/6 = X/24

X=(8X24) /6

X=32

C. (X+2) /25 =3/5

X+2= (3 X 25) / 5

X+2=15

X=15-2

X=13

D. (17-2X) / 7 =(X-3) / 2

(17-2X). 2 = (X-3) .7            [Multiplied by 14 on both side]

34-4x =7x-21

7x+4x=34+21

11x=55

x=5                                       [Multiplied by 11 on both side]

E. X² / 36 =1 / 4

X²= 36 /4

X²=9

X=±√9

X=±3
