Answer: x = 7, x = -15
Step-by-step explanation:
This is an absolute value equation, so it has to be simplified first
|x+4|+10=21
|x+4|=11
Then you set it equal to the two values it can be, getting rid of the absolute value sign.
x+4=11
x+4=-11
x = 7
x = -15
Voila!
The probability of the blue (question A) is going to be 0.3535 (C).
The probability of the white (question B) is going to be 0.7455 (D).
-> the probability (that none are white) = (9/12)(8/11)(7/10)(6/9) which = 14/55
the probability (that at least one of them are white) = 1- 14/55 which = 41/55
which makes your answer .7455 (this is the example of the white so you can see how I got the answer)
So for this, we will be simplifying √180 and √125 using the product rule of radicals (√ab = √a * √b)
Starting with √180: 
Now with √125: 
Now that we have our simplified radicals, our equation looks like this: 6√5 - 5√5 + √5 . Combine everything, and your answer will be 2√5.
Answer:
500 grams is 20 percent of 2.5 kg
Step-by-step explanation:
500*100 = 50,000
50,000/2500=20
