We have to solve x in terms of a, b and c:
a x - 3 b = c
a x - 3 b + 3 b = c + 3 b
a x = c + 3 b
x = ( c + 3 b ) : a
Answer:
4 ) ( c + 3 b ) / a
Answer:
Step-by-step explanation:

Answer: $432
Step-by-step explanation: If he marks up the price by 80% then you multiply the price (240) times 0.8, which is 192. That is how much he marks it up -- $192. SO then you add how much he marks it up to the original price of $242 which is $432.
Answer:
Step-by-step explanation:
4x+y=14
x-2y=8
then;
x=8-2y
substitute;
4(8-2y)+8-2y=14
32-8y+8-2y=14
40-10y=14
26=10y
y=2.6 , work out 4x+2.6=14 to get x
Answer: 12 sections of 1/16 acre
Step-by-step explanation:
We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.
This is equal to the quotient between 3/4 and 1/16
Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:
(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)
The quotient we want to solve is:
(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12
Then you can have 12 sections of 1/16 acre
