Answer:
0.25, 25%, or 1/4
Step-by-step explanation:
There are two possibilities for each coin: heads or tails. So the chance of getting heads for the first flip is 50%, or 1/2. To find the probability for both, you multiply 1/2*1/2 and get 1/4.
Your answer would be C. 5x+9y. <em>If you combine like terms and subtract the variable you will get your correct answer. I hope this helps.</em>
Answer:
Since we knew that the triangles are similar, we have:
19/38 = (x + 7)/(3x + 3)
=> 1/2 = (x + 7)/(3x + 3)
=> 3x + 3 = (x + 7) . 2
=> 3x + 3 = 2x + 14
=> 3x - 2x = 14 - 3
=> x = 11
4n + 7 - 5n ≥ 22
-n ≥ 15
n ≤ -15
