-18+x = 3 x = 3+18 x = 21
the fact family of the numbers 3, 6, and 18 is: 3 x 6 = 18; 6 x 3 = 18; 18 ÷ 3 = 6; 18 ÷ 6 = 3
18 = 2 x 3 x 3 36 = 2 x 2 x 3 x 3 GCF = 2 x 3 x 3 = 18
The GCF of 18, 36, and 54 is 18.The GCF is 18.
If you mean -x +x/3 = 12 then the value of x is -18 Check: --18 +(-18/3) = 12
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
2 x 3 x 3 = 18 3 x 3 x 5 = 45
1 x 18 2 x 9 3 x 6 2 x 3 x 3
2 x 3 x 3 = 18 2 x 2 x 2 x 3 = 24
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
31/3 of 18 = 31/3 x 18 = 3x3+1/3 x 18/1 = 10/3 x 18/1 = 10x18/3x1 = 180/3 = 60
