Hello from MrBillDoesMath!
Answer:
x = 7/8
Discussion:
3[x + 3(4x – 5)] = 15x – 24 =>
3x + (3*3)(4x-5) = 15x - 24 =>
3x + 9*(4x) - (3*3)*5 = 15x - 24 =>
3x + 36x - 45 = 15x - 24 => (add 24 to each side)
3x + 36x - 45 + 45 = 15x - 24 + 45 =>
39x = 15x + 21 => (as 45-24 = 21)
39x-15x = 21 => (subtract 15x from both sides)
24x = 21 =>
x = 21/24 = -7/8

Answer: 5225472000
Step-by-step explanation:
Given : The number of bulls = 6
The number of horses = 10
Since Aidan needs to place them in a line of 16 paddocks, and the bulls cannot be placed in adjacent paddocks .
Also there are two ways to arrange the group pf bulls and horses.
Then , the number of ways Aiden can place the bulls and horses in the paddocks so that no two bulls are paddocks will be :_

Hence, the number of ways Aiden can place the bulls and horses in the paddocks so that no two bulls are paddocks =5225472000
