Answer:
![x = 70](https://tex.z-dn.net/?f=x%20%3D%2070)
Step-by-step explanation:
Given
Molly: 50 out of 200
Joel: x out of 280
Required
Find x
Start by representing the giving parameters as ration
Molly= 50 : 200
Joel = x : 280
From the question, the ratios are equivalent. So,
![50 : 200 = x : 280](https://tex.z-dn.net/?f=50%20%3A%20200%20%3D%20x%20%3A%20280)
Convert to fractions
![\frac{50}{200} = \frac{x}{280}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B200%7D%20%3D%20%5Cfrac%7Bx%7D%7B280%7D)
Solve for x
![x = \frac{50}{200} * 280](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B50%7D%7B200%7D%20%2A%20280)
![x = \frac{1}{4} * 280](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20%2A%20280)
![x = \frac{280}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B280%7D%7B4%7D)
![x = 70](https://tex.z-dn.net/?f=x%20%3D%2070)
<span>The answer is one. First, these are both straight lines, meaning they will have one intersection point. In order to find the intersections of these two lines, we must set them equal to one another. So x + 5y = 6 equals 3x + 30y = 36. When you solve the two equations together, you'll get one intersection point at (0 , 1.2).</span>
