(<em>You</em><em> </em><em>can</em><em> </em><em>try</em><em> </em><em>dividing</em><em> </em><em>'</em><em>3</em><em>'</em><em> </em><em>by</em><em> </em><em>the</em><em> </em><em>other</em><em> </em><em>numbers</em><em> </em><em>to</em><em> </em><em>also</em><em> </em><em>check</em><em> </em><em>your</em><em> </em><em>answer</em>)
Hope this helped ^^
I believe you are referring to the half-life formula, which is used to calculate the half-life (when the substance drops to half of its original amount) of radioactive substances. The equation is as follows:

<em>A</em> is the remaining amount
<em>P</em> is the initial amount
<em>t</em> is the time that has passed
<em>h</em> is the half-life of the substance
When plugging values into the equation, make sure that <em>t </em>and <em>h </em>are both measured in the same unit (e.g. <em>t </em>days and <em>h </em>days), as well as <em>A </em>and <em>P</em>.
Answer:
The value of b is -42
Step-by-step explanation:
Parallel equations have identical or equal slopes. Given the form of the equation; y=5x+b and the point it passes through (8,-2) we determine the unknown value b by substituting x with 8 and y with -2. We solve the equation; -2 =5(8)+b to obtain b = -42
¼ is equal to 0.25 because when you times by 4 you get a whole :)
2x -4y=20
-4y=-2x+20
Y= 1/2x - 5 that’s the answer
