3.3g+4=1.3g+8 helppp pls

Solve |2x - 5| = 4 if anyone could , that would be great

Use the x-intercept method to find all real solutions of the equation.x^3-10x^2+27x-18=0

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?
