In order to solve equations like these, you need to move all terms involving the variable on one side, and all the numeric constants on the other side.
To do so, we can add/subtract the same quantity to both sides.
For example, we can add 5.2 to both sides to get
Then, we can add all the terms on the left hand side, and we have
Finally, we can divide both sides by -3.14:
In order to check the solution, we have to plug the value we found for x in the initial equation:
which is clearly true.
Answer:
Experimental probability of head = 2 / 5 or 40%
Step-by-step explanation:
Given:
Total chances of getting head = 20 times
Number of heads come = 8
Find:
Experimental probability of head
Computation:
Experimental probability of head = Number of heads come / Total chances of getting head
Experimental probability of head = 8 / 20
Experimental probability of head = 2 / 5 or 40%
Answer:
8 times
Step-by-step explanation:
2 x 8 = 16
64 + 16 = 80
10 x 8 = 80
Answer:
A. Selecting one person from a group of four boys and two girls.
