y=5, x=7 because if 3x5=15 then 15-7=8 dont report me if i do get this wrong
The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.
The entire equation should look something like 3 = 15(1/2)^t/4.95
The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.
The overall answer should be about 11.5 hours, as per an algebra calculator.
Hope this helps solve any other similar problems

10=x
Answer:
x < 1/6
Step-by-step explanation:
In the equation 10 – 2(3x – 1) > 6x + 10, start by using the distributive property. Once you've done that, you'd now get 10-6x+2 > 6x+10.
Now, add 10 and 2 togther to get -6x+12 > 6x+10.
Subtract 6x to both sides and subtract 12 to both sides and now you'll get
-12x > -2.
Now, divide each side by -12 to get x < 2/12 or 1/6. Notice how the sign is flipped since you divided by a -.
