The LCM is the lowest number that is a multiple of all three numbers. First, list the multiples of each number 8: 8, 16, 24, 32,40 48, 56, 64, 72, 80, 88, 96, 104, 112, 120 10: 10, 20, 30 40, 50, 60, 70, 80, 90, 100, 110, 120 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120
The LCM is 120 because there is no lower number that is a multiple of all three numbers. Hope this helped!
<span>Let x = represent the number of weeks of deposits A = 120 + 5x the account balance after x weeks The account balance is directly proportional to the number of weeks of deposits if: A/x = constant (120 + 5x)/x = 120/x + 5 is not a constant For example: After 1 week there will be: 120 + 1*5 = $125 on the account After 2 week there will be: 120 + 2*5 = $130 on the account After 3 week there will be: 120 + 3*5 = $135 on the account But 125/1 <> 130/2 <> 135/3 The account balance is not proportional to the number of weeks of deposits.</span>
The answer is the triangles could have the same shape( that is all the angles are equal) but the sides may not be the same length . Thay are similar but not necessarily congruent.
