I am a 5 digit number my 4 is worth 4*10000 my 3 is worth 3000 one of my 6 is worth 60 the other 6 is worth 10 times as much my other digit is 8

Initially 100 milligrams of a radioactive substance was present. after 6 hours the mass had decreased by 4%. if the rate of decay is proportional to the amount of the substance present at time t, find the amount remaining after 24 hours. (round your answer to one decimal place.)

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3
