You could do x=81 with the little line on the top (represents the number going on forever, and example is 0.818181818181818181818181818818181818 etc.)
Answer:
Below in bold.
Step-by-step explanation:
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
y - (-1)) = -2/5(x - -10)
y + 1 = -2/5(x + 10)
y + 1 = -2/5x - 4
y = -2/5x - 5.
In standard form this is:
2x + 5y = -25.
The equation to represent the relationship of the weights shown on the scale s 
The weights are given as:
The total weight on one side, where there are 4 small squares and 3 large squares is:
The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:
The weight of the triangle is x.
So, we have:
The weights on both sides are equal, because the scale is balanced.
So, we have:
Hence, the equation is

Answer:
z=13
Step-by-step explanation:
SU 1
------ = ------
WV 2
z 1
----- = ----------
z+13 2
Using cross products
2z = z+13
Subtract z from each side
2z-z = z+13-z
z = 13
it is false, there could be other reasons they wear a jacket other than being cold.
