6 x 9 x 3 = 162
When multiplying more than two numbers at a time it is easier to break it down into parts.
6 x 9 = 54
54 x 3 = 162
Also if you have a difficult time remembering your multiplication tables you can always add them because multiplying is similar to short hand adding.
For instance, if you count 6 nine times you will get 54 and then count 54 three times you will get 162.
6+6 = 12
12+6 = 18
18+6 = 24
24+6 = 30
30+6 = 36
36+6 = 42
42+6 = 48
48+6 = 54
If you count all the 6's there are nine altogether. From here you count 54 three times.
54+54 = 108
108+54 = 162
If you count all the 54's there are three.
To solve and get the above answer, you would do the following: First, write out the equations involved... X + Y = 9 and Y - X = 3 Now solve the first equation for X. x + Y = 9 is the same as X= 9 - Y now plug this into the second equation. Y - X = 3 becomes Y - ( 9 - Y ) = 3 which is the same as 2 * Y = 3 + 9 and this is the same as 2Y=12 which is Y= 6. now plug this answer back into the first equation to solve for X. X + Y = 9 becomes X + 6 = 9 which is the same as X = 3 So Y = 6 and X = 3 ... so 3 and 6 are your answers.
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
Please help me solve this 2x + 3 = 9 x =. x=3 because 2x3=6+3=9
(6/9) / (3/1) = (6/9) x (1/3) = 6/27
3x-3 = 6 3x = 6+3 3x = 9 x = 3
9 + x = 3 x = 3-9 x = -6 Check 9 + (-6) = 3 9 - 6 = 3
36/2=18 18/2=9 9/3=3 36/3=12 12/2=6 6/2=3 36/4=9 9/3=3 36/6=6 6/2=3
-6
x - 6 - 3 = x -9
x - 6 - 3 = x -9
X + 3 = 9 x + 3 - 3 = 9 - 3 x = 6
( 9+ ( 6 x 3 ) ) / 3 = 9
Both 6 and 9 have the number 3 as a prime factor. 6 = 3 x 2 9 = 3 x 3
To solve and get the above answer, you would do the following: First, write out the equations involved... X + Y = 9 and Y - X = 3 Now solve the first equation for X. x + Y = 9 is the same as X= 9 - Y now plug this into the second equation. Y - X = 3 becomes Y - ( 9 - Y ) = 3 which is the same as 2 * Y = 3 + 9 and this is the same as 2Y=12 which is Y= 6. now plug this answer back into the first equation to solve for X. X + Y = 9 becomes X + 6 = 9 which is the same as X = 3 So Y = 6 and X = 3 ... so 3 and 6 are your answers.
7^1 x 6^2 x x 9^3
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
7x - 3 = 6 + x 7x - x = 6 + 3 6x = 9 x = 9/6 = 3/2 = 1 and 1/2 or 1.5
