Answer:
130 calories in the ice cream and 500 calories in the pie.
Step-by-step explanation:
Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.
4x-20=500
If we add twenty to both sides, we end up with:
4x=520
Divide both sides by four, and you get x=130.
there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.

Answer:
--- Slope intercept
--- Standard form
Step-by-step explanation:
Given
The attached linear graph
Required
The equation
Select any two points on the line


Next, calculate the slope (m)

So, we have:


The slope intercept is then calculated using:

So, we have:



Multiply through bu 4

Subtract 3x from both sides
--- Standard form
