Answer:
y=3
Step-by-step explanation:
3x+2y=9
Let x =1
3*1+2y=9
3 +2y = 9
Subtract 3 from each side
3-3+2y=9-3
2y = 6
Divide each side by 2
2y/2 = 6/2
y =3
Answer:
Step-by-step explanation:
(x-5)2+8 = 92
2x-10+8 = 92
2x = 94
x = 47
Answer:
20.8%
Step-by-step explanation:
To find the final probability, two separate events must be done and the final propagation is the multiplication of these, like this:
First event:
Probability of black socks on Monday:
Total pair of socks: 1 + 3 + 5 = 9
Number of black socks on Monday: 3
Thus:
3/9 = 1/3
Second event:
Probability of white socks on Tuesday:
Total pair of socks: 8
Number of white socks on Tuesday: 5
Thus:
5/8
Final probability:
1/3 * 5/8 = 5/24
P = 0.208
So the probability would be 20.8%
3400/3600 to change seconds to hours = 0.94 hours
63360 / 5280 = 12 miles
12 miles / 0.94 hours = 12.77 miles/hour
