Juliana is trying to solve the problem below.The value of a used car is decreasing by $40 per month. How many months will it tak
e for the value to decrease from $5500 to $4300?Juliana solved the equation 5500 - 40m = 4300, and her solution was m = 30. Which problem-solving step was this?
If AB and CD are parallel lines and PR is the transversal, then angle PRD = angle APR by alternate interior angle theorem. Angle PRD = 120 degrees so, 65 + x = 120 degrees 120 - 65 = 55 degrees
