£750 is divided between Bridget, Caroline & Sarah so that Bridget gets twice as much as Caroline, and Caroline gets three times as much as Sarah. How much does Caroline get?

Caroline = 225

Step-by-step explanation:

Let Sarah be x

Caroline will be 3x

Bridget will be 2(3x) = 6x

x + 3x + 6x = 750

10x = 750

x = 750 / 10 = 75

Caroline gets 3x = 3 * 75 = 225

£225

Step-by-step explanation:

let x be the amount Sarah gets, then

Caroline gets 3x ( 3 times as much as Sarah )

Bridget gets 2 × 3x = 6x ( twice as much as Caroline )

Thus

x + 3x + 6x = 750, that is

10x = 750 ( divide both sides by 10 )

x = 75

Thus

Caroline gets 3x = 3 × 75 = £225

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
