2x + 2 -3x -15 > 0
-x-13 > 0
-x > 13
Answer: x < -13
Answer:
see below
Step-by-step explanation:
The experimental probability of heads is
P( heads) = 28/50 = 14/25
The theoretical probability is
P (heads) =1/2
Getting a common denominator for the experimental
25/50
comparing the experimental and the theoretical
28/50 > 25/50
experimental > theoretical
Answer:
I do not know the equations given but here's my equation and solution:
9x = 174°
x = 19 1/9°
Step-by-step explanation:
(3x + 2) + 2(3x + 2) = 180°
3x + 2 + 6x + 4 = 180°
9x + 6 = 180°
9x = 174°
x = 19 1/9

3(x-1) = 2x - y
3x-3 = 2x-y
3x-2x+y = 3
x + y = 3 ----> (1)
2(x+y) = 3+3y
2x + 2y = 3 + 3y
2x + 2y - 3y = 3
2x - y = 3 -----> (2)
make equation (1) and (2) together
x + y + 2x - y = 3+3
3x = 6
x = 2
now make x = 2 in equation (1)
x + y = 3
2 + y = 3
y = 3-2
y = 1
(x,y) = (2,1)
