Luna observed that in the last 12 issues of "rise over run weekly" 384 of the 960 pages contained an advertisement. if there are 80 pages in this week's edition, how many pages can she predict will have advertisements?

32 pages will have advertisements.

Step-by-step explanation:

As it has been given in the question that out of 383 pages out of 960 pages of "rise over the run" contained an advertisement.

We have to calculate the pages having advertisements using this information.

since 383 out of 960 pages have the advertisement which is 383×100/960=40%

Now if we have 80 pages in this week's edition then 40% of the total pages will have advertisement.

Number of pages with advertisements = 80×40% = 32 pages.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

answer: 5100 just subtract
