A number increased by four is the same as 19 minus 2 times the number

Answers

Answer 1
Answer:

From the information given, 4 added to the unknown number is equal to 2 times the unknown number when it is subtracted from 19.

Let the number be x

x + 4 = 19 - 2 (x)

We now expand and simplify the equation by placing unknown on one side and the known on the other side

x + 4 = 19 - 2x

x + 2x  = 19 - 4

       3x = 15

         x = 15 /3

          x = 5

If you decide to play a Pick 3 lottery game, in which you have to guess the exact order of the three numbers, what is your probability of winning? All 3 numbers will be between 0 and 9 and can be chosen more than once. A. 1/100 B. 1/1000 C. 3/1000 D. 1/720

Answers

Answer:

Option B is correct.

Step-by-step explanation:

We have been given that  3 lottery games have decided to play

So, here we have total possibility of numbers s between 0 and 9 which is total of 10 numbers

And number can be chosen more than once.

So, the probability will be (1)/(10)\cdot (1)/(10)\cdot (1)/(10)

On simplification we will get

the probability of winning (1)/(1000)

Therefore, option B is correct.
