Let's use x for Oana's age and y for her brother's age. That means
2y = x + 8
And Oana is 12 so...
2y = 12 + 8 --> 2y = 20 --> y = 10
Oana's brother is 10 years old now.

Find four consecutive even integers whose sum is 84. Find the integers.
mina [271]
Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.

The stock of Company A lost $4.17 throughout the day and ended at a value of
Anit [1.1K]

Answer:

4%

Step-by-step explanation:

After losing 4.17, it came down to 100.08, so the opening price was:

100.08 + 4.17 = 104.25

To find percentage decline, we find the ratio of the "change" (which is 4.17) divided by the opening (original) price, which is 104.25. Then we multiply that fraction by 100 to get our percentage decline.

So,

\frac{4.17}{104.25}*100=4

Thus, the

percentage decline = 4%
