Answer:
option D would be your answer
Step-by-step explanation:
(-x)+2•4/2=6
-x+8/2=6
-x+8=12
-x=4
x=-4
Because 3 2/4 would be the answer when you subtract it and most teachers and/or tests want you to simplify the answer which would be 1/2 because you would divide the numerator and denominator by 2.
3*8 = 24
You will have 24 sections.
Take a rectangle. Divide it into 8 equal sections
Repeat two more times. That will give you 24 equal peices.
<span>The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.</span>
