Calend 111 A rectangle has a perimeter of 34 meters. Its length, 1, is 2 more than three times its
width, w. Which system of equations can be used to find the length and width of the
rectangle?
Page 104
A 1+ w = 34
1 = 3w+2
B 21 + 2w = 34
1=3(w + 2)
Cl + W = 34
1 = 3 (2+2)
D 21+ 2w = 34
1 = 3 w + 2

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)
