Answer: 1/23
Step-by-step explanation:
Subtract 8x from both sides of the equation
from both sides of the equation
-15x = 8x + 1
-15x- 8x = 8x + 1 - 8x
Simplify
-23x = 1
Divide both sides of the equation by the same term
-23x = 1
=
Simplify
x = 1/23
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
It’s 360. Any shape will have a sum of 360, except for triangles, which are 180.
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
