Think About the Process Use the algebra tiles to help you solve the equation 4xminus12equals20. What is the first step in solving the equation using algebra tiles? What is the solution to the equation? What is the first step in solving the equation using algebra tiles? A. Divide each side of the model by 4. B. Add twelveminus1 tiles to each side of the model. C. Multiply each side of the model by 4. D. Add twelveplus1 tiles to each side of the model.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

you cant answer this dummy
