C=0.5x + 10
Where:
C = total cost of printing
x = number of business cards printed
0.5 = variable cost of printing, this cost depends on the number of business card
10 = fixed cost of printing, this cost stays the same regardless of the number of business card printed.
C = 0.5x + 10 ; derive the formula of x.
C - 10 = 0.5x
(C - 10)/0.5 = x
4 to the 18th power is the answer to your question.
The only ratio there equal to 6:3 is 54:27
Both 54 and 27 are divisible by 9.
54/9 = 6
27/9= 3
Therefore, 54:27=6:3

Find LCM of 12, 30, 66
------------------------------------------------------------------------------------
12 = 2² x 3
30 = 2 x 3 x 5
66 = 2 x 3 x 11
LCM = 2² x 3 x 5 x 11
LCM = 660
⇒ The 3 lights will flash simultaneously again 660 sec later

Calculate the next time the 3 lightships will flash simultaneously again
------------------------------------------------------------------------------------
6.00 am + 11 mins = 6.11 am
------------------------------------------------------------------------------------
Answer: The 3 lightships will flash at 6.11 am again

Answer:
y = 3/2x (This should be the correct answer do to the fact the slope is 3/2 and the points on here are 1, 1 which would most likely mean the y-intercept is 0. So we don't need to write the y-intercept on this equation.
