Opposite sides of a parallelogram are equal lengths, so ...
... AB = CD
... 6x +30 = 2y -10
and
... BC = AD
... 2x -5 = y -35
_____
The equations can be put in standard form to get
... 3x -y = -20
... 2x -y = -30
Subtracting the second from the first, we get
... x = 10
Solving for y, we have
... y = 2x+30 = 2·10 +30 = 50
The values of x and y are x=10, y=50.
_____
AB = 6x+30 = 90
BC = 2x-5 = 15
Answer:
9x-9
Step-by-step explanation:
the expression on the left simplifes to be 9x-8 so anything other than that will not produce a solution
examples: 9x+1, -9x-8, 10x+3, 12x . . .

Answer: 0.128
Step-by-step explanation:
The geometric probability of getting success on nth trial is given by :-
Given : The probability that he is successful on a given trial
.
Then , the probability that the third hole drilled is the first to yield a productive well is given by :-
Hence, the probability that the third hole drilled is the first to yield a productive well = 0.128
