Step-by-step explanation:
Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).
Based on the information provided in the problem, you know that the circumference of the circle is always as large as its radius.
Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to by "r".
Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":
Answer:
Equation : y = 4x + 55.50
x = 1.9 gigabytes
Step-by-step explanation:
Given that:
Flat fee per month = $55.50
Cost per gigabyte = $4
Let,
x be the number of gigabytes.
y be the total cost
y = 4x + 55.50
Lily wants to keep her bill $63.10
63.10 = 4x + 55.50
63.10 - 55.50 = 4x
4x = 7.60
Dividing both sides by 4
Hence,
Equation : y = 4x + 55.50
x = 1.9 gigabytes
