Answer:
4
Step-by-step explanation:
5 times 4 (20) + 7 times 4 (28) + 3 times 4 (12) = 60
Simplifying
7x = -3x + -60
Reorder the terms:
7x = -60 + -3x
Solving
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
7x + 3x = -60 + -3x + 3x
Combine like terms: 7x + 3x = 10x
10x = -60 + -3x + 3x
Combine like terms: -3x + 3x = 0
10x = -60 + 0
10x = -60
Divide each side by '10'.
x = -6
π/3
-5π/3 is a co terminal of 2π-5π/3= (6π-5π)/3=π/3
(5,0)=x1,y1
(0,3)=x2,y2
so the range will be x1-x2/
20
8/2 equals 4 and 5 x 4 = 20.
