PEMDAS (parenthesis, exponents, multiply, divide, add, subtract)
first you do parthesis (27/9) = 3
then you subtract from 10 [10-3] = 7
then multiply 3 (this is last because it is outside the parenthesis and [ ].
7 x 3 = 21
21 is your answer

If it gained 4 million people every 6 years, then the gain PER year would be 1.5 million. from 1992 to 2012 is 10 years. So, 1.5 times 10 is 15. 72 + 15 =87.
Your answer is 87 million.
Sqrt(220)= sqrt(2•2•5•11)=2 sqrt (5•11)=
2 sqrt(55)
So no the radical was not in it’s simplest form
Answer:
The balance is $18.
Step-by-step explanation:
You are in the negatives so you want to add so that your balance is positive.
1. -20 + 38 = x
x will be the variable that will be the final balance.
2. 18 = x
If you put this on a number line, you will see that when you add 38 to -20, your balance becomes 18. Therefore, your answer is 18.
X=11 for the first answer
