One car model cost $12,000 and cost an average of $0.10 per mile to maintain. another car model cost $14,000 and cost an average of $0.08 per mile to maintain. if one of each model is driven the same number of miles, after how many miles would the total cost be the same?

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

What number should be added to both sides of the equation to complete this square? x^2-10x=7

If a is a nonzero real number then the reciprocal of a is
