<span>The cost of each mile is $2.50.
If you simplify the expression given you will get the following.
y = 3.75 + 2.50(x - 3)
y = 3.75 + 2.50x - 7.50
y = 2.50x - 3.75.
Knowing that x is the number of miles and 2.50 is the number being multiplied by, we know that the cost per mile is 2.50. </span>

The circumference of Earth's equator is 40,080 km.
Step-by-step explanation:
Given that every 24 hours, Earth makes a full rotation around its axis, and Earth's speed of rotation at the equator is 1,670 km per hour, to determine what is the circumference of Earth's equator the following calculation must be performed:
24 x 1,670 = X
40,080 = X
Therefore, the circumference of Earth's equator is 40,080 km.
