Callie has a new kitten. The kitten weighs
Callie's cat. Together, the cat and the kitten wel
equations could be used to find the weight of each an
ne kitten weighs 3 pounds less than half the weight of
at and the kitten weigh 18 pounds. Which system of
A y = x + 3
y = -x + 18
B y = 1/x + 3
c y = 1/3x - 3
y = -x + 18
d y = 1/2x - 3
y = x + 18
= x + 18

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)
