C) 2 students
Explanation
Take Monday’s amount and subtract Friday’s
3-1=2
It’s -4 because you need to like distribute then add like terms, etc.
12/7 + 8/7
12+8 = 20
20/7 = 2 and 6/7ths
The correct answer is -1.
In order to solve this, we need to split into the positive and negative version of the answers. Let's start with the positive version.
2 - x < 4
-x < 2
x > -2 ----> NOTE: When we divide by -1, we have to change the direction of the sign.
Now we'll do the negative version.
2 - x > -4
-x > -6
x < 6
So we know the number must be greater than -2, but less than 6. The only number on this list that fits that is -1.
Answer:
the answer is B hope this helps you
