Answer:
a=(d-c)/b
Step-by-step explanation:
Subtract c from both sides:
ab+c−c=d−c
∴ab=d−c
Divide both sides by b
ab/b=d−c/b
so the answer is... a=(d-c)/b
<h3>Answer: 1/6</h3>
=========================================================
Work Shown:
A = area of black square
A = 2*2
A = 4
B = area of white symbol
B = (1/3)*A
B = (1/3)*4
B = 4/3
C = total area
C = 4*2
C = 8
Divide the values of B and C to find the fraction of the total area the white symbol covers up.
B/C = (4/3)/8
B/C = (4/3) / (8/1)
B/C = (4/3) divided by (8/1)
B/C = (4/3) times (1/8)
B/C = (4*1)/(3*8)
B/C = 4/24
B/C = 1/6

Answer:
90 minutes or 1 hour 30 minutes
Step-by-step explanation:
Time taken to fill t is inversely proportional to number of pipes. We can express this as t ∝ 
where n is the number of pipes
We can also write this as t = 
where k is a constant
Using the data given 80 = 
(1)
For 6 pipes, if the time taken is T then
(2)
Dividing (2) by (1) gives
÷
÷ 
So
T = 
(multiplying both sides by 80
And this computes to 90 minutes or 1 hour 30 minutes
