[YBC] / [ZYC] = 1/2

[PQRS] = (√20 + √48)²  

Very simple, is it not? 

Your answer is correct!!!        1/3(1/4) = 1/12

I should have divided 1/12 by 1/4               (1/12) / 1/4 = 1/3

Jack and Paul shared the total cost of a present for their father. Jack paid $48 more than 2/11 of the cost of the present. The ratio of the amount paid by Jack to the amount paid by Paul was 1:3. How much more did Paul pay for the present than Jack?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Jack's share = (2x/11) + 48

Paul's share = (9x/11) - 48

[(2x/11) + 48] / [(9x/11) - 48] = 1/3

x = 704

[(9x/11) - 48] - [(2x/11) +48] = 176

Paul paid $352 more than Jack.

fish burger => fb            chicken wing => cw

2 fb = 6 cw             2 fb + 6 cw = $1/4             2 fb = 1/8

Remaining money = 3/4

3/4(2/3) = 1/2

So, she bought 8 more fish burgers with 2/3 of her remaining money.

R = 3/4        W = 1/4

3/4(5/9) = 5/12    (Red beads)

1/2 - 5/12 = 1/12    (White beads)

∠B = 180 - 2x

∠y = 180 - x

(180 - 2x) + (180 - x) + 48 = 180

x = 76

∠B = 28º

FG = 6 + √525

Ethan bought a bag of marbles. After giving 1/5 of his marbles to Jacob and 105 marbles to Adam, he had 1/3 of the marbles left. How many marbles did Ethan buy?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

x - (x/5 + 105) = x/3

x = 225
