Which equation can be used to solve the problem?
juanita hiked 5 1/4 miles on saturday. that was 3/4 as far as laura hiked.
how far did laura hike?
a. m = 3/4 x 5 1/4
b. 3/4m = 5 1/4
c. 3/4 / m = 5 1/4
d. m - 3/4 = 5 1/4

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)

555.99.
