A particular isotope has a half-life of 74 days. If you start with 1 kilogram of this isotope, how much will remain after 150

$\bf \stackrel{150~days}{\textit{Amount for Exponential Decay using Half-Life}} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &1\\ t=\textit{elapsed time}\dotfill &150\\ h=\textit{half-life}\dotfill &74 \end{cases} \\\\\\ A=1\left( \frac{1}{2} \right)^{\frac{150}{74}}\implies A=1\left( \frac{1}{2} \right)^{\frac{75}{37}}\implies \boxed{A\approx 0.24536}$

Solve the equation: 4 - 5(3- 2x) = -2x + 1

Rufina [12.5K]

Answer:

x=1

Step-by-step explanation:

4 - 5(3- 2x) = -2x + 1

Distribute

4 - 15 +10x = -2x+1

Combine like terms

-11 +10x = -2x+1

Add 2x to each side

-11+10x+2x = -2x+2x +1

-11+12x = 1

Add 11 to each side

-11 +11 + 12x = 11+1

12x = 12

Divide each side by

12x/12 = 12/12

x = 1
