The answer is B:40 hours. You take 200 divided by 20 to get 10 (the amount of 20 page sections he needs to read) and then multiply 10 by 4 (the speed he reads).
Answer: 
Step-by-step explanation:
For this exercise you can use the following formula for calculate the slope:

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

Finally, evaluating, you get that the slope of this line is the following:

Answer:
I'm pretty sure A but let me know if I'm wrong
1. Zoe stacked the most brownies. She stacked 27 brownies out of the 50 brownies.
2. 15
3. 43 + 3n ≥ 70, so n ≥ 9
4. D. 58x + 13 + 58y
5. The answer would be ≤4
6. 9.94 + 10.01p ≤ 70, so p ≤ 6
7. C 40 89
8. D. x+(x+5)=77
