Need the graph in order to answer the question
She has 6 left.
70%= 0.7
0.7 x 20 = how many she has sold (14)
OR
30%=0.3
0.3 x 20= how many she hasn't sold (6)
Answer:
x=4, y=-2
Step-by-step explanation:
-5x+8y=-36
5x+7y=6
eqn 1+ eqn 2 gives
15y=-30
divide both sides by 15
y=-2, put in eqn 2
5x+7(-2)=6
5x=20 divide both sides by 5
x=4
A point is an exact location.
It has no length, width, or height.
It has no area or volume.
It has no mass, shape, or other physical properties.
As a model ...
-- you could use the period at the end of a sentence printed on paper.
It looks like this ==> ·
-- You could use the point of a very sharp pencil.
-- You could use the tiny dot that the point of
a very sharp pencil makes on paper.
-- You could use the point of a pin.
-- You could use the tiny hole that the point of
a pin makes in a sheet of paper.
These are all bigger than a real point. They all have a little bit of size,
length, width, height, and you can see them. But they get the idea across.
(They 'make the point'.)
