This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50
———————————-
4.5x = 85.50

Answer:
Step-by-step explanation:
The number of oranges with brothers be 6x, 4x , 2x
The brother with the largest share had 150 oranges. So,
6x = 150
x = 150/6
x = 25
4x = 4 * 25 = 100
2x = 2 *25 = 50
the number of oranges shared = 150+100 + 50 = 300 oranges

Hope it helps!!!
40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
