Answer:
4 PAIRS OF SOCKS
Step-by-step explanation:
50-24.95=25.05
25.05/5.95
4 pairs of socks
Z < 6. Just divide each side by 5 :)
Answer:
This situation of the recipe can be represented as y=x+5.5 and it is expected that x is ≥ 0 and y is ≥ 5.5.
What is the equation for this situation?
It is known the total amount of flour (y) is equivalent to the total amount of whole wheat flour (5.5) added to the total white flour (x). Therefore, the equation is:
y = x + 5.5
The possible values are
x = It is expected x is equalthan 0 or greater to it since the minimum amount of white flour that can be added is 0.
y = It is expected y is equal than 5.5 or greater to it since even if no
white flour is added the minimum total is 5.5.

Explanation:
Note that:

=

Hence the (positive) square root of
8
is somewhere between
2
and
3
. Since
8
is much closer to
9
=
3
2
than
4
=
2
2
, we can deduce that the closest integer to the square root is
3
.
We can use this proximity of the square root of
8
to
3
to derive an efficient method for finding approximations.
Consider a quadratic with zeros

√

and

From this quadratic, we can define a sequence of integers recursively as follows:

The first few terms are:

,

,

,

1189
,

,
...
The ratio between successive terms will tend very quickly towards

√

.
So:
