The answer is D because 3 can’t go to different numbers on the x column
1) Value of x is: x= 5.39
2) Value of w = 125
3) Value of a = 74.21
Step-by-step explanation:
1. x + 6.8 = 12.19. What is x
We need to find the value of x
Adding -6.8 on both sides of the equation
![x + 6.8 = 12.19\\x+6.8-6.8=12.19-6.8\\x=5.39](https://tex.z-dn.net/?f=x%20%2B%206.8%20%3D%2012.19%5C%5Cx%2B6.8-6.8%3D12.19-6.8%5C%5Cx%3D5.39)
So, value of x is: x= 5.39
2) 0.05w = 6.25. How do I answer this?
We need to find value of w
Dividing both sides of equation by 0.05
![0.05w = 6.25\\\frac{0.05w}{0.05}=\frac{6.25}{0.05}\\w=125](https://tex.z-dn.net/?f=0.05w%20%3D%206.25%5C%5C%5Cfrac%7B0.05w%7D%7B0.05%7D%3D%5Cfrac%7B6.25%7D%7B0.05%7D%5C%5Cw%3D125)
So, Value of w = 125
3) a/9.05 = 8.2. What is a?
We need to find value of a
Multiplying both sides by 9.05
![\frac{a}{9.05}=8.2](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B9.05%7D%3D8.2)
![\frac{a}{9.05}*9.05=8.2*9.05\\a=74.21](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B9.05%7D%2A9.05%3D8.2%2A9.05%5C%5Ca%3D74.21)
So, Value of a = 74.21

Answer:
3cm
Step-by-step explanation:
A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length
Area of a parallelogram = base x height
18cm² = 6cm x height
height = 18cm² / 6cm = 3cm
