It is 54.
Multiplication is similar to short hand for adding. If you have a difficult time remembering your multiplication tables you can always figure it out by adding.
For instance, if you add 9 six times you will get 54.
9+9 = 18
18+9 = 27
27+9 = 36
36+9 = 45
45+9 = 54
If you count all the nine's there are six total. If you were to add 6 nine times you will also get 54 in the same way.
6 _ or 6/9. Six Ninths :) 9 That is incorrect. 2/3 x 9 = 6 Answer is 6.
X + 6*9 = X + 54
Two stamps
9 + x = 3 x = 3-9 x = -6 Check 9 + (-6) = 3 9 - 6 = 3
9 x 6 = 54
The postage for a 6 x 9 envelope would depend on the weight of it.
The postage for a 6 x 9 envelope would depend on the weight of it.
6 _ or 6/9. Six Ninths :) 9 That is incorrect. 2/3 x 9 = 6 Answer is 6.
9(6 + x) = 1
because they divide into 6 evenly - no remainder
X + 6*9 = X + 54
3
9 with 9 remaining 144 - 9 = 135 = 15 x 9
Two stamps
9 + x = 3 x = 3-9 x = -6 Check 9 + (-6) = 3 9 - 6 = 3
9 x 6 = 54
