Answer:
b = -23.5
Step-by-step explanation:
4.7(3x - 5) = 14.1x - 23.5
Lets start this by seeing what Rose has done:
first she borrows $5, then she borrows another $11. she then pays back $3.50 of the $5 and $9.50 of the $11.
knowing this, we can use a number line to help solve this problem. first, we would make a mark at 5 on your number line, then go up the number line 11 more times until you reach 16. once youre at 16, you need to jump backwards down the number line 3 1/2 spots. this would leave you at 13 1/2, which would leave a dot halfway in between 13 and 14. now, you need to back 9 1/2 more spots so you can see how much she owes to her brother and father. if youre at 13 1/2 on your number line, and go back, or subtract, 9 1/2 spots you end up 4. this means that Rose owes $4 still. if you do not understand this process, i will include a picture below of my number line and you can follow along to the steps written above on the number line.
let me know if you have any other questions

Answer: B represents 7
This problem is asking us to find halfway between 2 and 12.
[Method One]
12 - 2 = 10
-
10 / 2 = 5
-
2 + 5 = 7
<em>or</em>
12 - 5 = 7
[Method Two]
[Method Three]
We can count up from 2 and down from 12 until we hit the middle
2 12
3 11
4 10
5 9
6 8
7 7
