Answer:
-2/5
Step-by-step explanation:
Slope of a line is also called gradient.
Let A(x₁,y₁) and B(x₂,y₂) be points on a certain line;
slope = (y₂ -y₁)/(x₂ - x₁)
In this question the 2 points that lie on the line are: (-5,5) and (0,3)
slope = (3 - 5)/(0 - -5)
= -2/5
Perimeter: 2 1/8 + 3 1/2 + 2 1/2 = 7 (1 + 4 + 4)/8 = 7 9/8 = 8 1/8

Answer: 140
Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.
Let the number of toys Oleg has = x
Let the number of toys Sasha has = y
Let the number of toys Dima has = z
Sasha had twice as many toys as Oleg
So y = 2*x= 2x
Dima had 40 more toys than Oleg.
z = x + 40
Oleg, Sasha, and Dima shared 600 toys
x + y + z= 600
We know y=2x and z=x+40
Replace it for y and z
Subtract 40 on both sides
Divide by 4 on both sides
Oleg had 140 toys
