Astudent wants to reduce the size of an article he found in a newspaper. the original article was 12 cm wide. he needs to reduce it so its width measures 9cm. on the copier, what percent setting should he can use to make a copy this size? i use time4 learning homeschool website, and it used incorrect wording, which might confuse you, but this is exactly how the question is stated. !

the answer is 90% and i use Time4learning as well so i know how it feels when no one is around to help but the answer is 90% hope it helps.

Step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
