ACT Math Practice Questions and Answers.
408. 04 is the correct answer. If you divide 2,727 miles by 27 miles per gallon you will get the number of gallons: = 101. Then, multiply the number of gallons by the cost per gallon: 101(4.04) = 408.04. This gives the cost of gas for this car to travel 2,727 typical miles. 14 is the correct answer. When you use x = 3 and y = 5 in the given expressions, 3x² - 2y = 3(3)² - 2(5) = 27 - 10 = 17 and 2x² - 3y = 2(3)² - 3(5) = 18 - 15 = 3. Then subtract 3 from 17 to get 14.
