Solve for p. 2 (p + 1) = 16

A. p = 7

B. p = 7.5

C. p = 8.5

D. p = 9

p=7

Step-by-step explanation:

2(p + 1) = 16

2p + 2 = 16

     -2      -2

2p = 14

/2     /2

p=7

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)
