I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11
Explanation: The anglers in a triangle must all add to 180.
Therefore, we can use the equation 180=3x+28+5x+52+2x-10
Combing like terms gives us 180=10x+70
Solving for x gives us 11.
To check our work, we can plug in 11 for x.
3(11)+28+5(11)+52+2(11)-10=180.

Step-by-step explanation:

-3x + 9 - 4 = x + 3 + 2x
-3x + 9 - 4 = 3x + 3
9 - 4 = 6x + 3
5 = 6x + 3
2 = 6x
1/3 = x
6.974 rounded to the nearest tenth is 7.0, because 7 is more than 5, and since 9's there, we make that 6 to a 7.
Answer:
Domain: all real numbers
Range: less than/equal to -2
Assuming the coin is fair, probability of getting one tail is 50%, probability of getting two tails in a row is 50%*50% = 25% or 1/4
