Answer:
4.78x
Step-by-step explanation:
how've 7,.8*x 3n by 6y is =4.78x
-3x + 2y = -3
4x - y = -1
2(4x - y = -1)
-3x +2y = -3
8x -2y = -2
-5x = -5
/-5
X = 1
Answer:
23 x + 62
Step-by-step explanation:
Simplify the following:
5 (4 x + 12) + 3 x + 2
5 (4 x + 12) = 20 x + 60:
20 x + 60 + 3 x + 2
Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):
(20 x + 3 x) + (60 + 2)
20 x + 3 x = 23 x:
23 x + (60 + 2)
60 + 2 = 62:
Answer: 23 x + 62
I would think the value would be .2 cause if you had 100 tosses you would expect 60 value for heads and -40 value for tails. giving you 20/100
