( 9+ ( 6 x 3 ) ) / 3 = 9
No, 9 is divisible by 3 and 9, but not six 3 x 9 = 27, also not divisible by 6
Multiples of 9 and 6 are also divisible by three, the reverse is not true. 15 is divisible by 3, but not 6 or 9. 27 is divisible by 3 and 9, but not 6. 12 is divisible by 3 and 6, but not 9. 54 is divisible by 3, 6 and 9.
(9+3) - (2 +4) = 6
3
-3 -6 - -9 -6 = -6+9-6 = 3 - 6= -3
3 + -9 = 3 - 9 = -6 (negative 6)
3.
9 - 3 = 6
6
Let's see. If the smallest number is x, then the largest one is 2x + 9. Then, x + 2x + 9 = 5x - 3 (we assume that this is true) 3x + 9 = 5x - 3 subtract 5x and 9 to both sides -2x = -12 divide by -2 to both sides x = 6 Since x = 6, then 2x + 9 = 2(6) + 9 = 12 + 9 = 21. check: 6 + 21 = 5(6) - 3 ? 27 = 30 - 3 ? 27 = 27 True
3 and 6 yes, 9 no.
