a)
there are total 3 diffrent shades
because
(i) A = C = 1/2 so one shade
(ii) B=D =F = 2/3 so one shade
(iii) E = 5/8 one shade
so total 3 different shade
b )
(i) y = 1/2 b
(ii) y = (2/3) b
(iii) y = 5/8 b
Answer:
I have not J.H.S 3 , because the questions look like some J.H.S 3 ,so please I am very sorry that I can't help u in this questions . Thanks
What exactly are you trying to find?
Part A
We have x = 4 and y = 3 paired up together.
This says that 4 pounds of potatoes cost $3
The price per pound (aka unit price) is y/x = 3/4 = 0.75 dollars = 75 cents.
Answer: 75 cents per pound
========================================
Part B
The ordered pair (8,6) means x = 8 and y = 6 pair up together.
So in this case, 8 pounds of potatoes cost $6.
notice how y/x = 6/8 = 3/4 = 0.75 dollars = 75 cents here as well. So we get the same unit cost.
