Question

Halla el valor de x en cada simplificación.

40/32=5/x

180/450=x/5

12/1728=x/144

13/x=1/13

Answer 1

40/32=5/x

40 (x) = 32 (5)

40x = 160

x = 160/40

x = 4
------------------------------------------

180/450=x/5

180 (5) = 450 (x)

900 = 450x

900/450 = x

2 = x
----------------------------------------------


12/1728=x/144

12 (144) = 1728 (x)

1728 = 1728x

1 = x
-------------------------------------------------

13/x=1/13

(13 * 13) = x (1)

169 = x
