Answer:
x=6
Step-by-step explanation:
x + 6 = x + x original problem
x + 6 = 2x combine like terms
-x = -x subtract x from both sides to have like terms on each side
6 = x solution
The inequality is: x*0.75 + 3.00 < 20.00, where x represents the number of miles. When you solve the inequality, you get 22.66 miles. When you round up to 23 miles, you don't satisfy the inequality, so you have to round down to 22 miles.
Answer: (C) 22 miles
