Step-by-step explanation:
ln(x) + ln(x + 25) = 0
ln(x(x + 25)) = 0
ln(x² + 25x) = 0
ln(x² + 25x) = ln(1) , x ≥ 0
x² + 25x = 1
x² + 25x + 625/4 = 1 + 625/4
(x + 25/2)² = 629/4
x + 25/2 = ±√(629/4)
x = ( -25 ±√629)/2
x = (-25 - √629)/2 atau ( -25 + √629)/2
(-25 - √629)/2 ≥ 0 NOT PROVED
(-25 + √629)/2 ≥ 0 PROVED
Solution → x = (-25 + √629)/2

Answer:
A. 4.50 B. 1 : 3
Step-by-step explanation:
A.
First, think of Toby's money as 1/6x (x referring to the total amount of money) and Daoud's money as 1/2x.
It states that Toby gets 1.50, which means that 1/6x = 1.50.
To find what x is, multiply both sides by 6.
1/6x * 6 = 1.50 * 6
x = 9
Now that we know how much money there is in total, we can solve for Daoud's money. Daoud has 1/2x. We can substitute x for 9 and solve for Daoud's money.
1/2(9)
4.50
Daoud has 4.50.
B.
The problem states that Elsa gets the remaining money.
9 - (1.50 + 4.50)
9 - 6
3
Elsa gets 3.00.
Now, you can use turn solve the ratio of Toby's money and Elsa's money.
1.5 : 3
The problem states that they have to be whole numbers, so you can change the ratio to fit the requirements.
1 : 3
