Step-by-step explanation:
Area of circle 1 = πr²
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²
Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²

Answer:
The variable is t
t represent the cost of movie tickets
Step-by-step explanation:
Given:
Total cost = 7t + 4.50
The variable is t
Michael + 6 friends = 7 people
4.50 represent the cost of popcorn
t represent the cost of movie tickets
For instance,
If the cost of a movie tickets is $2
Then,
t = 2
Total cost = 7t + 4.50
= 7(2) + 4.50
= 14 + 4.50
= 18.50
Total cost = $18.50
It has no solution because x is always the same amount. So.. for example.
lets say x = 10.
then it would be 10 + 2 = 10 + 3.
12 doesnt = 13. :)
