Answer:
x = 7 units
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
5 cm 3 cm
------------------ = ------------------------
(40 + 5) cm (3 + 2x + 10) cm
This simplifies to:
5 3
-------- = -----------
45 2x + 13
Solve for x. Cross-multiplying, we get:
10x + 65 = 135, or x = 7
So x = 7 units.

Answer:

The graph in the attached figure
Step-by-step explanation:
Let
x-----> the number of pints
y----> the number of servings
For x=3 pints, y=2 servings
This is a proportional variation
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
so
The linear equation is equal to
