Answer:
5 binders
Step-by-step explanation:
3 times 5 binders would be 15$, and since he paid with 20$, that is 5 dollars change
As an algbraic equation:
3x+5=20
3x=15
x=5
The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

Answer:
see attached graph
Step-by-step explanation:
Given equation: 
Standard form of a quadratic equation: 
where 
is the y-intercept
If 
then the parabola opens upwards.
If 
then the parabola opens downwards.
Therefore, the y-intercept of the graph is (0, 3)
To find the x-intercepts, factor the equation:
Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)
To determine the vertex, differentiate the equation:
Set to zero and solve for x:
Substitute 
into the original equation and solve for y:
Therefore, the vertex (or turning point) is at (2, -1)
Hello!
Vertical angles are always congruent
This means that 3x - 35 = 130
We can solve this algebraically
3x - 35 = 130
Add 35 to both sides
3x = 165
Divide both sides by 3
x = 55
The angle AOB and AOC are supplementary which means they add to 180
First we have to find what angle AOB equals
3(55) - 35 = 130
We can subtract 180 by this number to get angle AOC
180 - 130 = 50
Angle AOC is 50
The answers are x = 55 and AOC = 50
Hope this helps!
