Javier has 4 boxes of comic books. the mean number of books in each box is 25. which number line shows what could happen to the mean if he fills two more boxes, one with 26 comic books and one with 30 comic books?

Well, if the mean of each box is 25 think of it this way Javier could add 25x4+26+30.

Step-by-step explanation:

This is how it is done because you have to take the other boxes and mulpliy by 25 cause if u just add the 25 then u are only using one box. then when u multiply you add the rest at followed. Make sure that the number line reads exact.

And here is a tip: when u are posting a question with graphs or number lines or anything that has pictures that u need help with make sure to include the graphs or whatever. u can do this by using snipping tool witch is a screen shot tool.

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
