Answer: They collected 13,204 cans more than needed.
Add the digits together and if 3 will divide evenly into the answer, it is divisible by 3
For instance:
6 + 9 = 15
15 /3 = 5
3 divides into 15 evenly so 69 is divisible by 3
3x-5y =15
2x-y=-4
multiply the equation by 5 and then subtract equation 2 from equation 1
so 3x-5y =15
10x-5y =-20
-7x =35 x =-5
plug in the value of x in the second equation -10 -y =-4 - y= -4 +10 y =-6
x=-5 y=-6
The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).
<h3>What is point slope form?</h3>
The point slope form of a line is the expression of line which has a specified slope and passes through a point.
The point slope form is givne as,
(y-y₁)=m(x-x₁)
Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.
The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,
(y-y₁)=m(x-x₁)
(y-(-1))=-5(x-2)
(y+1)=-5(x-2)
Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

Note how angle GFE forms a right angle, which is 90 degrees.
Since the line cuts that angle into two smaller angles, intuitively, these angles add up to 90 degrees.
So, we can say that 2x + 3x = 90 (angle sum of right angle)
5x = 90
x = 18 degrees
