Solve for x,
6(x - 1) = 9(x + 2)
x = -8

11

x = - 8

Step-by-step explanation:

Given

6(x - 1) = 9(x + 2) ← distribute parenthesis on both sides

6x - 6 = 9x + 18 ( subtract 9x from both sides )

- 3x - 6 = 18 ( add 6 to both sides )

- 3x = 24 ( divide both sides by - 3 )

x = - 8

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
