crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723

[See Below]

Step-by-step explanation:

✦ So it must add up to 360dg so add:

✧ 115dg + 85dg + 60dg = 260dg

✦ Now subtract:

✧ 360dg - 260dg = 100dg

So X would be 100 degrees.
