1. ALL
2. 10,3,-1,-5,-11
3.-1/2, -2/3, 7/12, 0.82
Since there are a total number of 15 members participating, you would divide 150 by 15 since everyone would get their fair share. Next you would multiply 10 by 9 which would result to $90 and the profit the math club received
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
Answer:
D. 80, 140, 70
Step-by-step explanation:
80°, 140° and 70° cannot form a triangle as the total number of the three angles is 290° whereby the total number of angles in a triangle is 180°
The length of a diagonal of a square is the side*sqrt(2). Let's call one side of the square: s
So we have 18 = s*sqrt(2)
18/sqrt(2) = s
18sqrt(2)/2 = s
9sqrt(2) = s
Since the perimeter is 4 sides we multiply by 4 to get 36sqrt(2) as the perimeter.
