These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
l-18l=18
Answer: 219.375 miles
<u>Step-by-step explanation:</u>
d = r * t
= 67.5 * 3.25
= 219.375
X=750+125.75x
subtract to variable (x) on one side
x-125.75x=750+125.75x-125.75x
-124.75x=750
divide -124.75 to get variable (x) by itself
-124.75x/-124.75=750/-124.75
x=-3000/499
or
x=-6 6/499
or
x=-6.01202
2 meters = 200 centimeters
