Answer:
if x is the number of miles driven, the equation is 2.25x + 12=30. solved: x = 8 miles
Step-by-step explanation:
First, you make the equation. If x is the number of miles, the price per mile would be 2.25 times x or 2.25x. You also have to add the one time fee of $12, so you have 2.25x + 12. Next, you're trying to find x if it costs $30 total so you would have 2.25x + 12 = 30.
Solving,
2.25x + 12 = 30
subtract 12 from both sides
2.25x = 18
divide both sides by 2.25
x = 8 miles

Let us solve the first two fractions : The LCM of 3 and 4 is 12



LCM of 2 and 12 is 12

Take 3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together
=83
Now you divide 83 by the number of terms in the sample set, which is 20.
83/20 = 4.15
For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.
final answer= 4.2
