Each pencil should be sold for 6
6*20 = 120 which is a 20 profit
20% is 0.2, so it is greater.
Answer:
The slope of the line is -5/4
Step-by-step explanation:
19) = Solution :-
5x+4y = 20
Let's keep x's value 0,
so
we get,
5x+4y = 20
or, 5×0+4y = 20
or, 4y = 20
so, y = 5
one coordinate we get (0,5)
Again
Let's keep x's value 4,
we get,
5x+4y = 20
or, 5×4+4y = 20
or, 20+4y=20
or, 4y = 0
so, y = 0
Another coordinate, we get (4,0)
now
slope(m) = (y2-y1)/(x2-x1)
= (0-5)/(4-0)
= -5/4
Answer:
That is 6 divided by 3/8, better written as
6
--
1
====
3
--
8
Invert the 3/8 and then multiply:
6 8
-- * ---
1 3
Reduce 6/3: 6/3 = 2
Then you have 2(8), or 16 (answer)
