54 because there are 12 inches in a foot 12 divided by 3 is 4 and 6 divided by 3 is 2. Add the 2 and 4 and multiply that by 9
Answer:
total amount = n (d-18)
total amount = dn - 18n
Step-by-step explanation:
given data
pay = $18 less than the original price
originally cost = d dollars
sell = n games
solution
we take original price paid for the game = d
and they will pay $18 less than the original price
so that can we say
d -18
and
when sold n games than the cost of n used games will be here
cost = n (d-18)
so it can express as
total amount = n (d-18)
total amount = dn - 18n
Given that: step 1

step 2: subtract 3x both side

Step 3: Add 18 both side:

Step 4: divide both side by 5

Step:6 The value of x is:
x=6
