Answer: r = 3
Step-by-step explanation:
Step 1: Cross-multiply.
2r = 12/18
(2)*(18)=12*r
36=12r
Step 2: Flip the equation.
12r=36
Step 3: Divide both sides by 12.
12r/12 = 36/12
r = 3

Answer:
The width of rectangle w = 4 units
Step-by-step explanation:
We are given:
Width of rectangle = w
Length of rectangle = w+ 4
Area of rectangle = 32 units
We need to find width of the rectangle
The formula used is: 
Putting values and finding width of rectangle
We need to solve this quadratic equation to find width (w)
We will use factorisation and break the middle term.
Since width of rectangle can't be negative, so rejecting w=-8
Therefore, the width of rectangle w = 4 units
Answer:
When number of games downloaded is at least 3
Step-by-step explanation:
Let x = number of games downloaded
Members = 50 + 2x
Non members = 20x
50 + 2x = 20x
50 = 20x - 2x
50 = 18x
x = 50/18
x = 2.78
At x = 2.78, both members and non members are paying the same amount
For members to make profits, the value of x must be greater than 2.78
Approximately x = 3
Check:
Members = 50 + 2x
= 50 + 2(3)
= 50 + 6
= 56
Non members = 20x
= 20(3)
= 60
