4 x 6 - 1.5= (4 x6) -1.5 = 24 - 1.5 = 22.5
4, 6 and 15 or 46 and 15 cos 4,6 and 15 LCM is 360 (4 x 6 x 15)
x/6+4=15-4 -4x/6=11*6 *6x=66
15 + 3 - (6 x 4) = -6
60. 4 = 22 6 = 2 x 3 15 = 3 x 5 lcm = 22 x 3 x 5 = 60
Therefore: x = 4
15/10 = 6/4
3x2 + 4x - 15 = 0, solve by using the quadratic formula. a = 3, b = 4, c = -15 x = [-b ± √(b2 - 4ac)]/(2a) x = [-4 ± √(42 - 4*3*-15)]/(2*3) = [-4 ± √(16 + 180)]/6 = (-4 ± √(196)/6 = (-4 ± 17)/6 x = (-4 +17)/6 = 13/6 or x = (-4 - 17)/6 = -21/6 = -7/2 The solution set: {-7/2, 13/6}.
Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.
4/15 x 4/4 = 16/60 3/10 x 6/6 = 18/60 11/15 x 4/4 = 44/60 17/20 x 3/3 = 51/60 9/10 x 6/6 = 54/60
1 x 30, 2 x 15, 3 x 10, 4 x 7.5, 5 x 6, 6 x 5, 10 x 3, 30 x 1 all equal 30.
4/6 x 15 = 10
4 x 6 - 15 = 9. (:
