Answer:
(300 + 50x)/(2 + x)
Step-by-step explanation:
Let the cost of teachers' edition books be t
Let the cost of students' edition books be s
So t = 150; s = 50
Then the total cost of 2 teachers' editions and x students' editions is 2t + sx = 2 × 150 + 50x = 300 + 50x.
The total number of books is 2 + x.
So the average cost per book is (300 + 50x)/(2 + x)

Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.
Hope this helps!
