Y=3

Step-by-step explanation:

23. y =3 because if the shorter base is 8 you add 8+4 because the longer base is x+4 and x=8 then when you add 8+4 you get 12 and once you get 12 you find out the 12+6=26 so you have to divide the 6 by two because you have 2 legs and that gives you 3 and 3+3=6 so you have your answer

hope this helped!!!...

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)
