Answer:
2/3x - 3 = 5
Step-by-step explanation:
Let x be the number
2/3x - 3 = 5
Add 3 to each side
2/3x-3+3 = 5+3
2/3x = 8
Multiply each side by 3/2
3/2*2/3x = 8*3/2
x = 12
Answer:
7 millicuries
Step-by-step explanation:
A period of 10 days is 2 times the half-life of 5 days.
In the first 5 days, the amount of the chemical decayed by half from 28 millicuries to 14 millicuries. In the next 5 days, it decayed by half again, from 14 millicuries to 7 millicuries.
10 days later, 7 millicuries of the chemical remains.
For the answer to the question above.
<span>There is already an answer inside the question.
"You're correct that the man has a 50% probability of carrying the Huntington's allele.
Now, if he does have it, the probability that his first child will also inherit the Huntington's allele is also 50%.
But there is only a 50% chance that the man has it to give to his son. So:
.5 X .5 = 0.25 = 25%
There is a 25% chance that the man's first child will be affected by Huntington's disease."</span>
$35,000. $43,750 / 125 % = 35,000.
she’s making $10,750 more than she was last year.
