Step-by-step explanation:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
56 = 2 ×2 × 2 × 7
Now
Common factor = 2
Remaining factor = 2 × 3 × 2 × 3 × 7
LCM = RF × CF
= 504
hence the lCM of 12 , 18 and 56 is 504...

Every number will have only 3 digits. In the ones place, there are 5 choices. For every choice of digit made in the ones place, there are 8 possible choices for the hundreds place (you can choose from 1-9, omitting whatever is used in the ones place), and there are 8 possible choices for the tens place (you can choose from 0-9, omitting whatever has already been used elsewhere).
So there are

such numbers.
Answer:
Kelvin wrote 60 the wrong way.
He has to write $30.65 - 60%, not 0.60.
Here is the final correct equation:
$30.65 - 60% = 12.26
Answer:
the amount that need to be paid by her is $633.60
Step-by-step explanation:
The computation of the amount that need to be paid by her is shown below:
= Purchase value of merchandise - purchase value fo merchandise × discount rate
= $720 - $720 × 12%
= $720 - $86.4
= $633.60
hence, the amount that need to be paid by her is $633.60
Answer:
d. no solution
Explanation:
Step 1 - Subtract nine from both sides of the equation

Step 2 - Remove the absolute value

Therefore, since positive two is not less than or equal to negative two, there is no solution.
