Simplify 1st equation
2x-y=-2
simplify second equation
-x+y=5
add both equations
2x-y=-2
-x+y=5
------------
x =3
-x+y=5
-3+y=5
y=8
x=3, y=8
He running of the simulation serves to give us an approximate probability of each of the outcomes, so in this case, P(Tails)=66/100 and P(2)=18/100.The probability of two independent things occurring can be written as P(A)*P(B).Therefore, the probability of a 2 and tails is (66/100)*(18/100)=0.1188= 1188/10000
Idk I have tried and failed miserably
At most, 20. 20 is the greatest common factor of all numbers.
Answer:
x = 50
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Therefore, add together the expressions for all 4 angles, equal to 360, and solve for x:
(2x + 15) + (3x - 20) + x + (x + 15) = 360
Gather like terms: 2x + 3x + x + x + 15 - 20 + 15 = 360
Combine like terms: 7x + 10 = 360
Subtract 10 from both sides: 7x = 350
Divide both sides by 7: x = 50
