3> -5+m/2 solve for the varible "m"

For this case we must solve the expression given for the variable "m":

We add 5 to both sides of the inequality:

Multiplying by 2 to both of the inequality:

So, finally we have:

The solution is given by all values of m less than 4.

the answer is c. 23/3

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)
