Delia, Edwin and Freya share some money in the ratio 5:7:8 Freya's share is £1600 how much did they share?

andrey2020 [161]

Answer: £ 400,560,640

Step-by-step explanation:

Given

Delia, Edwin, and Freya share £1600 in the ratio $5:7:8$

Suppose, their shares are 5x,7x, and 8x such that the ratio remains the same.

The sum of their shares must be £1600

$\Rightarrow 5x+7x+8x=1600\\\Rightarrow 20x=1600\\\\\Rightarrow x=\dfrac{1600}{20}\\\\\Rightarrow x=80$

Their share is

Delia: $5\times 80=400$

Edwin: $7\times 80=560$

Freya: $8\times 80=640$

What is the value of y2 – x2 when y = 6 and x = 5?

Papessa [141]

Answer:

y^2 - x^2 = 11

Step-by-step explanation:

y^2 - x^2 = ?

Substitute.

y = 6

x = 5

Becomes:

6^2 - 5^2 = ?

Solve.

6^2 = 6 x 6

6 x 6 = 36

5^2 = 5 x 5

5 x 5 = 25

36 - 25 = 11
