Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104

Answer:
8
Step-by-step explanation:
Simplify the expression.
Any number larger than 36 would be a counter examples.
When n is equal to 36, both sides of the inequality are equal to 216. As you get larger than 36 the right side is larger than the left side. Therefore, the inequality is not true.
Divide the 1st equation by 2:
Divide the 2nd equation by 3:
Therefore, when we subtract the exact the 1st equation by the 2nd equation:
Substituting back into the 2nd equation will give:
