This question is ratio based.
So 460:12
        ? : 3
To get from 12 to 3, you divide by 4 (3 is 1/4 of 12)
So...
Divide 460 by 4 too
460/4 = 115 dives in 3 hours

In the equation below, what is the value of b? 4(x-2)^2-7=ax^2+bx+c

Svetach [21]

Answer:

Jan brought 44 cookies

Step-by-step explanation:

To solve this problem, we need to work backwards. First, we have 10 cookies left at the end of the day. At lunch, she gave away 12 cookies. This means that Ms. Jan had 22 cookies at lunch since  

10 + 12 = 22

In the morning, Ms. Jan gave out half of her cookies. This means that she started with twice as many cookies as she had at the beginning of lunch.  

22  x 2 = 44

Ms. Jan brought 44 cookies.
