Answer:
A.
Step-by-step explanation:
The given equation is
![3x-7y=14](https://tex.z-dn.net/?f=3x-7y%3D14)
We solve for y by subtracting 3x from both sides to obtain;
![-7y=14-3x](https://tex.z-dn.net/?f=-7y%3D14-3x)
We now divide through by -7 to get;
![y=\frac{-3}{-7}x+\frac{14}{-7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-3%7D%7B-7%7Dx%2B%5Cfrac%7B14%7D%7B-7%7D)
This simplifies to;
![y=\frac{3}{7}x-2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B7%7Dx-2)
This equation is now in the form y=mx +c, where
is the slope.
Answer:
The original price was $312.50
Step-by-step explanation:
If the vacuum was marked down by 20%, that means it was sold for 80% of the full price. It was sold for $250, so 80% of the original price is $250.
Let's set up an equation.
80/100 of x = 250
0.8 • x = 250
Divide both sides by 0.8.
x = 312.50
The original price was $312.50
Hope this helps!

4 different streets with 5 customers on each means 4*5 customers or 20 customers. If he has 20 customers and he gets $10 from each one, thats 20*10. he collected $200
Opposite operation of multiplication = division.
![65/5.45 = 11.93](https://tex.z-dn.net/?f=65%2F5.45%20%3D%2011.93)
Simply divide 65 by 5.45
