The equation should look like :
[H+] = (1-a)(x) + (a)(y)
Where:
5.8 = -log [H+]
5.0 = -log x
6.9 = -log y
(1-a) = proportion of x
<span>a = proportion of y
so calculating a will give you the result of how many ounces are required</span>
The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
─── ∙ ~εïз~ ∙ ───
answer: 16
how? 100/4 = 25
3/4 = 0.75 because 25 x 3 = 0.75
0.75x = 12
12/0.75 = 16
Answer:
12 and 16
Step-by-step explanation:
it just means what ever number is greater
