Answer: 55.7 m2
Step-by-step explanation:Step 1
3x2=6
3x9.9=29.7
10x2=20
Step 2
6+29.7+20=55.7
We can calculate the age by using the formula: final amount=initial amount*(1/2)^(time/half-life), or t=ln(final amount/initial amount)/(-0.693)*half-life. The half life of C-14 is 5730 years, and final amount=initial amount is 51% or 0.51, so t=ln(0.51)/(-0.693)*5730=5567 years approximately.
Add 8 to both sides: -4x>-12
Divide both sides by -4: x>3
Flip the sign since we divided by a negative: x<3
So the correct answer is B

Answer:
5
Step-by-step explanation:
-2x - y = -3
y = -3x + 2
-2x - (-3x + 2) = -3
-2x + 3x - 2 = -3
x = -1
y = -3*-1 + 2 = 5
