Step-by-step explanation:
x-19=1
x=1+19
x=20
Answer:
24
Step-by-step explanation:
To evaluate this, we just need to substitute 2 for whenever we see x.
40 - 8 (2)
From here, we can just use order of operations to simplify it down to a single number.
40 - 16
24
So, when x = 2, we get 24.
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
The total cost will be $56 because 3 x 8 = 24 so then you multiply 7 x 8 = 56.
