Find the value of x when (a) 9 : x : : 54 : 48 (b) 2, 6 , x are in continued proportion

a) x = 8

b) x = 18

Step-by-step explanation:

Given that

9 : x : : 54 : 48

This may be rewritten as

9/x = 54/48

cross multiply

9 * 48 = 54 * x

Divide both sides by 54

x = 9 * 48/54

= 8

b Given that 2, 6, x are in continued proportion then

2/6 = 6/x

2 * x = 6 * 6

x = 36/2

= 18

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the answer is d
