Answer:
C = 0.75(n/2)
Step-by-step explanation:
For each pair of signs, $0.75 is needed for the posterboard.
C = 0.75(n/2)
This can be simplified to ...
C = 0.375n . . . . for n an even number
__
If posterboard only comes in the size given, then the more technically correct answer is ...
C = 0.75·ceiling(n/2)

Answer:
See explanation below
Step-by-step explanation:
Explain what is the difference between the solutions to 2x=10 and 2x > 10
Given the equations;
2x = 10
x = 10/2
x = 5
For the equation 2x > 10
x > 10/2
x > 5
The first equation has only one solution which is 5 while the second equation has infinite number of solutions since the values of x can take any value that is greater than 5
Answer:
The smallest positive number is 8
Step-by-step explanation:
let the smallest positive number = x
45 is a multiple of 9 ⇒ 9 x 5 = 45
the next multiple of 9 after 55 is 63
= 9 x 7
= 63
Thus, x + 55 = 63
x = 63 - 55
x = 8
The greatest common factor of 45 and 63 = 9
Therefore, the smallest positive number is 8

Answer:
$96
Step-by-step explanation:
Morgan worked 48 -40 = 8 hours of overtime. The pay for each of those hours is 1.5×$8 = $12.
