% rate= (19/24) x 100% = 79.17%
Let x and y be the unknowns. Based on the given problem, we have: x + y = -19 [The sum of two numbers is -19] xy = 24 [The product of two numbers is 24] Solve for these numbers either by elimination or substitution method. The recommended choice is substitution method. Solve for y for the second equation: y = 24/x Substitute that expression for the first equation: x + (24/x) = -19 Solve for x by rearranging the terms: x² + 24 = -19x [Multiply both sides by x] x² + 19x + 24 = 0 Since the expression can't be factored, you don't get integers for x and y. Let's complete the square, and see what we have: x² + 19x + (19/2)² = -24 + (19/2)² (x + (19/2))² = 66.25 x + (19/2) = ±√(66.25) or ±√(265/4) x + (19/2) = ±√(265)/2 x = (-19 ± √(265))/2 Finally, substitute that value back for either of the equation and solve for y. You should get: y = ±24/((-19 ± √(265))/2) = ½(-19 ∓ √265) So the numbers are: x = ½ * (-19 - √265) and y = ½ * (√265 - 19) y = ½ * (√(265) - 19) and y = ½ * (-19 - √265)
The Least Common Multiple (LCM) for 19, 23, and 24 is 10488.This is 19 x 23 x 24 because 19 and 23 are prime numbers and non of the three have common factors.
24 x 3 x 19= 912
Each part equals -19. 0-19=-19, 4-23=-19,...so 25-X=-19. This means 25+19=X, so the missing number is 25+19 which is 44.
48 = 24 x 3 24 = 23 x 3 8 = 23 19 = 19 LCM = 24 x 3 x 19
19 is already prime. 2 x 2 x 2 x 3 = 24

To convert a fraction to a percentage multiply by 100: 19/24 = 19/24 x 100 % = 791/6 % ≈ 79.167 %
The Least Common Multiple (LCM) for 19, 23, and 24 is 10488.This is 19 x 23 x 24 because 19 and 23 are prime numbers and non of the three have common factors.
(19 x 0.05) + (43 x 0.1) + (24 x 0.25) + (14 x 0.5) = $18.25
24 x 3 x 19 = 912
24 x 3 x 19= 912
24 x 3 x 19 = 912
24 19 - 11 = 8 8 x 3 = 24 so 19 - (24/3) = 19 - 8 = 11
