8,000

That is because 7 is larger than 5, so we round up.

Answer: 8,000

It would be 8,000...
7 ---> up a value which is 8
(7+1=8)
When we're doing these type of problems always look carefully at the value the problem is asking, in this case ten hundredth which is the 7
Hope that helps!

HELP ME PLEASEEEEEEEEEEEEEEEEEE

Mice21 [21]

Answer:

y = 3/2x + 15

Step-by-step explanation:

change f(x) to 'y='

interchange 'x' and 'y' then solve for 'y':

y = 2/3x - 10

x = 2/3y - 10

x+10 = 2/3y

multiply each side by 3/2 to get:

y = 3/2x + 15

There are 143076 books in the library. The 3rd grade class walked over and each kid checked out 2 books. There are 21 students i

9966 [12]

Answer:

The answer is: There are only 143034 books left after the students return to their classroom

Step-by-step explanation:

Lets call X= Number of books left in the library after the students return to their classroom.

B=Total of Books in the library

S=Total of books taken by the 3rd grade students

If each student of the 3rd grage class take 2 books, the total of book taken by the 3rd grade students would be:

S=2 books per student * Total of students of the 3rdgrade

S=2*21=42

Then we must substract Total of Books in the library minus Total of books taken by the 3rd grade students. That would be:

X=B-S

X=143076-42

X=143034

I hope that this answer will help you
