Answer: ![\frac{5}{4}\leq x\leq 2](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D%5Cleq%20%20%20x%5Cleq%202)
Step-by-step explanation:
Given :
5 ≤ 4x− 1 < 7
the equation could be spitted into 2
1. ![5\leq 4x](https://tex.z-dn.net/?f=5%5Cleq%204x)
ii. ![4x - 1](https://tex.z-dn.net/?f=4x%20-%201%20%3C7)
solving them separately , we have
![5\leq 4x](https://tex.z-dn.net/?f=5%5Cleq%204x)
divide through by 4
![\frac{5}{4}\leq x](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D%5Cleq%20%20x)
solving (ii) we have
![4x - 1](https://tex.z-dn.net/?f=4x%20-%201%20%3C7)
add 1 to both sides
![4x < 7 + 1](https://tex.z-dn.net/?f=4x%20%3C%207%20%2B%201)
![4x < 8](https://tex.z-dn.net/?f=4x%20%3C%208)
![x](https://tex.z-dn.net/?f=x%3C2)
combining the solutions , we have ![\frac{5}{4}\leq x\leq 2](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D%5Cleq%20%20%20x%5Cleq%202)
Answer
the notebooks are 20% of the overall weight due to 70% being textbooks and the other 6 pounds or 30% being the bag and note books and with 2/3 of 30% being 20% then the text books are 13 pounds i used 4 x 3 1/2 but that's just my guess

Answer:
-15
Step-by-step explanation:
x-1/2(x+5)=-10
x-1/2x-5/2=-10
2/2x-1/2x-5/2=-10
1/2x-5/2=-10
1/2x=-10+5/2
1/2x=-20/2+5/2
1/2x=-15/2
x=(-15/2)/(1/2)
x=(-15/2)(2/1)
x=-15/1
x=-15
