What reciprocal would be used to solve the equation 3p=-12

P=8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*p-12-(12)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  3p - 24  =   3 • (p - 8)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    p-8 = 0

Add  8  to both sides of the equation :

                     p = 8

One solution was found :

                  p = 8

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)

the answer is b.)
