The mystery number is 8 or in decimal is 8538.01. hope its correct.
The answer is -2. To do this, combine all like terms then solve for x by dividing.
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as, 
.
It is known that, when height i.e. 
meter, then velocity 
m/sec.
So, we get the formula as, 
.
Now, when the hammer hits the ground, the height 
meter.
Thus, we have,
⇒ 
⇒ 
⇒ 
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
Answer:
If an event is affected by previous events then it is a dependent event, while if an event is not affected by the previous event then it is an independent event.
Since we have replaced the card that we first drew from the deck, it wont affect the event of pulling a card second time.
So, we can say that it is an example of independent event.
The given equation does not have any solution.
For given question,
We have been given an equation −5a + 5a + 9 = 8
We know that the like terms are those terms which have same variable to the same power.
Combine Like terms;
0 + 9 = 8
9 = 8
⇒ which is False.
This statement is false for any values of x
Therefore, the given equation does not have any solution.
