1. 5x-8x+12-6
-3x+6 <this is the answer
You would take the number of pounds you want to buy (3.5) and multiply it by how much it costs per pound ($3.48).
It will look like this
(3.5)(3.48)

Step-by-step explanation:
we know that
In the unit circle
The coordinates of a point have the following rule
where
(x,y) are the coordinates of the point a r is the radius
but remember that in a unit circle the radius is equal to 1
so
<em><u>Find the x-coordinate of each case</u></em>
Part 1) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 2) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 3) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 4) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
