Step-by-step explanation:
![-3+\sqrt{2x-1} =8](https://tex.z-dn.net/?f=-3%2B%5Csqrt%7B2x-1%7D%20%3D8)
![\sqrt{2x-1} -3=8](https://tex.z-dn.net/?f=%5Csqrt%7B2x-1%7D%20-3%3D8)
<u><em>Add 3 to both sides of the equation:</em></u>
![\sqrt{2x-1}-3+3=8+3](https://tex.z-dn.net/?f=%5Csqrt%7B2x-1%7D-3%2B3%3D8%2B3)
![\sqrt{2x-1}=11](https://tex.z-dn.net/?f=%5Csqrt%7B2x-1%7D%3D11)
<u><em>Solve the square root:</em></u>
![\sqrt{2x-1}=11](https://tex.z-dn.net/?f=%5Csqrt%7B2x-1%7D%3D11)
![2x-1=11^{2}](https://tex.z-dn.net/?f=2x-1%3D11%5E%7B2%7D)
![2x-1=121](https://tex.z-dn.net/?f=2x-1%3D121)
<em> {add 1 to both sides}</em>
![2x=122](https://tex.z-dn.net/?f=2x%3D122)
![x=122/2](https://tex.z-dn.net/?f=x%3D122%2F2)

Answer:
The answer to your question is 32 rose and 8 tulip
Step-by-step explanation:
Data
rose/ 4 = tulip
total number of arrangements = 40
Rose arrangement = R = ?
Tulip arrangement = T = ?
Process
1.- Write equations to solve this problem
R/4 = T
R + T = 40
2.- Solve the system by substitution
R + R/4 = 40
(4R + R) / 4 = 40
4R + R = 4(40)
5R = 160
R = 160 / 5
R = 32
- Find T
32 + T = 40
T = 40 - 32
T = 8
3.- Conclusion
She made 32 rose arrangement and 8 tulip arrangements.
Answer:
1. 32 inches = 81.28 centimeters
2.402 000 millimeters = 402 meters
3. 2.85 meters = 285 centimeters
4.2 kilometers= 2000000 millimeters
5. 71 meters = 0.071 kilometers
6. 8kg = 8000 g
7. 3000 g = 3 kg
8. 2.5 kg = 2500 g
9 850 mg = 9.85 g
10.75 dg = 1075 m
120^ is the answer for this problem
