Step-by-step explanation:


To solve this system of equation, let's multiply the second equation by two so both equations have a
:


Next, let's add the two equations together to remove the
and solve for
:



Now that we have the value of
, we can plug it into either of the equations to solve for
:




or




Therefore, the solution to this system of equations is
.
Answer: P = 0.28
Step-by-step explanation:
If we pick it at random, the probability of selecting each tile must be equal. this means that the probability of picking a tile of a giving color is equal to the number of the tiles of that color divided the total number of tiles.
We have 14 beige tiles and 20 + 14 + 16 = 50 tiles in total.
Then the probability of piking a beige tile is:
P = 14/50 = 0.28
For number 1. Is 21 = 21
Number 2. 12/25
Number 3. 9
Number 4. 64 =64
Number 5. 15 = 5
Number 6. 4= 4
For number 3, write something along the lines in your own words like The risks involved in the use of condoms in combating the spread of HIV and AIDS is the condom can break, the condom can be slipped off without knowledge, and the condom does not protect from oral sex.
