7(3) - 15/(5). 7 x 3 is equal to 21, 15/5 is equal to 3. you are now left with 21- 3,
Answer:


Step-by-step explanation:
First we define two generic vectors in our
space:


By definition we know that Euclidean norm on an 2-dimensional Euclidean space
is:

Also we know that the inner product in
space is defined as:

So as first condition we have that both two vectors have Euclidian Norm 1, that is:

and

As second condition we have that:


Which is the same:

Replacing the second condition on the first condition we have:

Since
we have two posible solutions,
or
. If we choose
, we can choose next the other solution for
.
Remembering,

The two vectors we are looking for are:

Answer:
140/56= 2,5$ every hot dog
175/2,5=70 hot dogs
70-56=14 more hot dogs to earn 175$
