Answer:
4 books
Step-by-step explanation:
First you add up the lunch and gym clothes together which is 3. Then you subtract 19 (the total of weight she can carry in her bag) by 3 and you get 16. 16 divided by 4 which is the weight of each book gets you 4, the answer.
The correct graph would be graph c.
First lets start by making the denominators the same. I multiplied the 4 by 5 and 10 by 2.
-25/20 = x -14/20
Add 14/20 on both sides (do the opposite to cancel out and whatever you do to one side you need to do to the other.
You should get -11/20 = x
It would be D because you have to do the cube root on both sides. What I do is ignore the decimal and add it in later once the math is complete like on this question you can tell by process of elimination that 8 squared is 64 but you’re look for the cube root so that eliminates a and c and now just make sure the decimal is in the right place
