Answer:
4 weeks : 5 books
8 weeks : 10 books
Step-by-step explanation:
alright so she is reading at a rate of 1.25 books per week, we know this becasue we can divide 15/12 which is equal to 1.25. Know we know the rate we can just multiply the rate by the number of weeks, so 4 * 1.25 = 5, and 8 * 1.25 = 10.
The absolute value sign makes it so that k+7 could be either -3 or +3 and the result would still be 3. This means there are two possible answers for k. The one that makes k+7=-3 and the one that makes k+7=+3. Just solve these two equations:
k+7=-3
k=-3-7
k=-10
k+7=3
k=3-7
k=-4
So the possible answers are -4 and -10. B is the correct choice.
