A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would cost for this car to travel 2,727 typical miles? - 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. When x = 3 and y = 5, by how much does the value of 3x² - 2y exceed the value of 2x² - 3y ? - 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. What is the value of x when 2x + 3 = 3x - 4 ? - The answer is 7. You can solve this problem by first subtracting 2x from each side of the equation to get 3 = x - 4. Then add 4 to each side, so x = 7.
