Iwill give 11. = 18 to y 12. z to 4= 13. 9 to 15= 15; y

Step-by-step explanation:

18^y = 4/6        Take the log of both sides

log(18^y) = log(4/6)

log(18^y) = y * log(18)

log (4/6) = - 0.17609

y * log(18) = y * 1.25527

So

y = - 0.17609 / 1.25527

y = - 0.14056

Check

18^-0.14056 = 0.6661 which is close enough to 0.666666666

z^4 = 8/5                        Take the log of both sides.

log(z^4) = log(8/5)          Simlplify the left. Take the log of the right.

4 * log(z) = 0.20416        Divide by 4

log(z) = 0.20416 /4

log(z) = 0.051029          Take the antilog of both sides.

z = 10^(0.051029)

z = 1.12467

Check

1.12467 ^ 4 = 1.6 which is what it should be.

I can't really make out the third one.

hi i’m going tomorrow morning and i can come over and you out with this stuff for me haha ya day is going crazy and i’ll tell you what i’m talking about you don’t wanna go do you think i’m going to be a good friend i just don’t know how much you mean about the stuff you want to do and stuff you know i just want you and you know that i’m going crazy i don’t think i’m going crazy about going tomorrow and i’ll tell ya hey i don’t think i’m going crazy about going tomorrow and i’ll tell you what i’m done
