the sum of three numbers is 64. the second number is 3 less than the first number, the third number is 11 less than twice the first. what are the three numbers?
Number one = x Number two = y Number three = z x + y + z = 26The second number is twice the first. y = 2x The third number is 6 more than the second. z = y + 6 z = 2x + 6 x + 2x + (2x + 6) = 26 5x = 20 x = 4 Number one = 4 Number two = 8 Number three = 14
joan decided to use her calculator to find the sum of the first 15 counting numbers instead of the formula. By mistake she entered 16 numbers. She entered one number twice . Her answer was 4 more than a perfect square number. Which number did joan enter twice?
Let x represent the first number; 2x - 3 then represents the second number. x + 2x - 3 = 75 3x = 78 x = 26 2x - 3 = 49 So the numbers are 26 and 49.
