Answer:
x = 10
Step-by-step explanation:
4x + 3(x - 1) = 67 ← distribute parenthesis and simplify left side
4x + 3x - 3 = 67
7x - 3 = 67 ( add 3 to both sides )
7x = 70 ( divide both sides by 7 )
x = 10
Answer:
34.85%
Step-by-step explanation:
Let w be the probability of winning, then probability of losing would be (1 - w)
We know the ratio of winning to losing is 0.535
w/(1 - w) = 0.535
w = 0.535 - 0.535w
1.535w = 0.535
w = 0.348534202
% of games won:
0.348534202 × 100
34.8534202%

One third the difference of A and B = 
Here, as given in the question:
Now, one third of the difference is :
Hence, one third the difference between 3/4 and 2/3 is
Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
