The theoretical probability would be 10/20 but the experimental probability was 7/20.
Answer:
x = -2
Step-by-step explanation:
3x -8 =8x +4/2
3x -8 =8x +2
3x -3x -8 = 8x -3x +2 (subtract 3x both sides )
-8 = 5x +2
-8-2 =5x+2 -2 (subtract 2 both sides )
-10 =5x
-10/5 = 5x/5 (divide 5 both sides)
-2 = x
The answer is D. None of these.
As answer A. would be angle 6,4 and 5,3
B. Angles 6,3 and 5,4
C. Angles 8,4 7,5 5,1 6,2
Answer:
x=-9,y=-4
Step-by-step explanation:
2x-3y=-6...(1)
-2x-2y=26...(2)
To solve we will have to eliminate one of the given variables, the variable to be eliminated is x
And it can be done by adding up (1) and (2)
It gives
-5y=20
Divide both sides by-5
y=-4
Then substitute the value of y into (1)
2x-3(-4)=-6
2x+12=-6
Substrate 12 from both sides
2x=-18
Divide both sides by 2
x=-9
Therefore x gives -9 and y gives-4
