Answer:
13
Step-by-step explanation:
-12 - - 25 =
- 12 + 25 =
13
Let x equal the number of tiny book boxes and y equal the number of large book boxes.
Because John must pack at least 35 boxes:
(number of tiny book boxes) + (number of large book boxes) = (at least) 35
x + y ≥ 35
Since John needs to pack at least 350 books:
(number of small books packed) + (number of large books packed) (is at least) 350
(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350
15x + 8y ≥ 350
Your system of inequalities is:
x + y ≥ 35
15x + 8y ≥ 350

Answer:
Second Option: 
Step-by-step explanation:
A fraction means to divide.

Therefore,

3A+2B=20
2A+B=13 ➡×(-2)➡-4A-2B=-26
3A+2B-4A-2B=20-26
-A=-6 ➡A=6
2(6)+B=13➡B=1
