Answer:
1
Step-by-step explanation:
Hello,
2x – 1 = 1 – 2x
<=> 2x-1+2x=1
<=> 4x-1=1
<=> 4x = 1+1=2
<=> x = 2/4 = 1/2
Then there is only one solution.
Thanks
I think its c your welcome

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:
- -3 ÷ -3 = Cancels Out
- Turns into:
![\frac{-9}{-3} >5x-2](https://tex.z-dn.net/?f=%5Cfrac%7B-9%7D%7B-3%7D%20%3E5x-2)
✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:
- -9 ÷ -3 = 3
- Turns into:
![3 > 5x - 2](https://tex.z-dn.net/?f=3%20%3E%205x%20-%202)
✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:
- Turns into:
![5x-2](https://tex.z-dn.net/?f=5x-2%3C3)
✺ Add 2 to both sides:
- Turns into:
![5x](https://tex.z-dn.net/?f=5x%3C3%2B2)
✺ Add 3 and 2 to get 5:
- 3 + 2 = 5
- Turns into:
![5x](https://tex.z-dn.net/?f=5x%3C5)
✺ Divide both sides by 5. Since 5 is positive, the inequality direction remains the same:
- 5 ÷ 5 = Cancels Out
- Turns into:
![x](https://tex.z-dn.net/?f=x%3C%5Cfrac%7B5%7D%7B5%7D)
✺ Divide 5 by 5 to get 1:
✺ So your answer is B,

Answer:
y = dependent variable
k = constant of proportionality or constant rate of change
x = independent variable
Step-by-step explanation:
The equation,
represents a direct variation showing a proportional relationship between variable y and variable x.
y represents the dependent variable
k represents the constant of proportionality or constant rate of change
x represents the independent variable
Answer =37.5 rows of two
Explanation= you can do 75 divid by 2 to get rows of two each of 75.
