Answer:
x = 25
Step-by-step explanation:
2/5x - 1 = 9
Add 1 to both sides
2/5x = 10
Multiply by 5 on both sides
2x = 50
Divide by 2 on both sides
x = 25
Check the answer:
Plug in 25 for x
2/5(25) - 1 = 9
10 - 1 = 9
9 = 9
The answer is correct.
5 is to 7 as is to 49 is to 51
Answer:
the 3 represent a one thousand
so that means 4.oo9* 1000 = =49
The "one head and one tail" would be my best guess because you get one of each outcome, whereas the other two outcomes are two of the same outcome.
