26. sunnyday elementary school is having its annual read-a-thon. the third graders have read 573 books so far. their goal is to read more than 900 books. what is the least number of books they need to read to reach their goal? explain.

327 books are needed to be read.

Step-by-step explanation:

Let the 3rd graders have to read the total number of books = x

Since they have read 573 books s far so number of books left to read = (x - 573)

If x = 900

then minimum number of books to be read by 3rd graders = 900 - 573

= 327 books

Therefore, 327 books are needed to be read.

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
