If j represent the number of jelly beans in each box, then the equation that models the problem is; 6j = 324
<h3>How to model an equation?</h3>
We are told that the principal used 6 small boxes of jelly beans to fill a large glass jar.
Now, each box had the same number of jelly beans, for a total of 324 jelly beans.
If j represent the number of jelly beans in each box, then the equation that models the problem is; 6j = 324

Answer:
x = 5/2, y = -1
x*y = 5/2*-1 = -5/2
Step-by-step explanation:
First we solve the system
2x-5y = 10
x = 5 + 5y/2
4x + 3y = 7
4(5 + 5y/2) + 3y = 7
20 +10y + 3y = 7
-13 = 13y
y = -1
Now go back to the other equation
2x - 5y = 10
2x - 5(-1) = 10
2x + 5 = 10
2x = 5
x = 5/2
Now we multiply x and y together
Answer:
66
Step-by-step explanation:
11 + 4 = 15
90 / 15 = 6
6 * 11 = 66

See explanation
Step-by-step explanation:
Given
![-2(5x+8)=14+6x](https://tex.z-dn.net/?f=-2%285x%2B8%29%3D14%2B6x)
Required
Complete the steps
![-2(5x+8)=14+6x](https://tex.z-dn.net/?f=-2%285x%2B8%29%3D14%2B6x)
Multiply 5x and 8 by -2
![-10x - 16 = 14 + 6x](https://tex.z-dn.net/?f=-10x%20-%2016%20%3D%2014%20%2B%206x)
Subtract by 6x
![-10x - 6x- 16 = 14 + 6x - 6x](https://tex.z-dn.net/?f=-10x%20-%206x-%2016%20%3D%2014%20%2B%206x%20-%206x)
![-16x- 16 = 14](https://tex.z-dn.net/?f=-16x-%2016%20%3D%2014)
Add 16
![-16x- 16 + 16= 14 + 16](https://tex.z-dn.net/?f=-16x-%2016%20%2B%2016%3D%2014%20%2B%2016)
![-16x= 30](https://tex.z-dn.net/?f=-16x%3D%2030)
Divide by -16
![x= \frac{30}{-16}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B30%7D%7B-16%7D)
![x= -\frac{15}{8}](https://tex.z-dn.net/?f=x%3D%20-%5Cfrac%7B15%7D%7B8%7D)
