n= 5/4
n= 1 1/4
So the final answer is n= 1.25
Answer:

Step-by-step explanation:
Since it is -1, put 1/something
The sale on Friday = x = 6
The sale on Saturday = x+2 = 6 + 2 =8
The sale on Sunday = x+4 = 6+4 =10
Step-by-step explanation:
Let x be the sale of Friday
Then
x+2 will be the sale of Saturday
x+4 will be the sale of Sunday
According to the given statement, that the total sales were 24

The sale on Friday = x = 6
The sale on Saturday = x+2 = 6 + 2 =8
The sale on Sunday = x+4 = 6+4 =10

Answer:
When you join points D(2,3),O(0,0)and E(5,1) which are not collinear it will form a triangle.
Now , Adjacent of ∠ DOE are [ ∠ ODE and ∠OED] .
As we know that Sum of three interior angles of a triangle is 180°.
∠ DOE + ∠OED+∠EDO = 180°
∠DOE=180°- (∠OED+∠EDO)
Supplementary ,of ∠DOE is (∠OED+∠EDO).
