Let x represent the first number, then x-7 represents the second number

Assume the numbers are whole numbers (no negative numbers), then the smallest value that x could be is 8. Thus, the first number is 8 and the second number is 1. The LCM is 8.

Let's increase x by one number so that x=9, then the second number is 2. The LCM is 18.

Let's increase x again by one number so x=10, then the second number is 3. The LCM is 30.

You could continue this to discover that the LCM will be x(x-7) between x=8 and x=13.

So what happens at x=14? First digit is 14 and the second digit is 7. The LCM is 14.

This will occur for all x-values that are multiples of 7.

Answer: when x is a multiple of 7, the LCM is x. when x is not a multiple of 7, the LCM is x(x-7).

There are approximately 4.3 weeks in each month. How much will you take home each month after taxes?​
Marianna [84]

Answer:

So roughly c x c = b/100

5 x 5 x 100 = $2500

Step-by-step explanation:

Lets say c = 5 and b = 1

= 5c =100c/5c x b

= 20c x b

We can also show

= 20c x b =5c

c = 20c/5c x b = 5c

1/20 x 5c = 5c

b=1

One example is 20%  = 0.20 x 500 = 100c  

=  7.12c  = 7c

1= 100%

100 x 71.042  = 710.42 weekly pay. emergency tax 142 = 568

100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107

710-107 = 603 a week

4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29
