First, you want to solve for the equation for this problem, would be:
0.05N + 0.10D = 20.50
While N = The amount of nickels, and D = The amount of dimes.
Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.
Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.
0.05N + 0.10D = 20.50
<span>0.05(164) + 0.10(123) = 20.50
</span><span>8.2 + 12.3 = 20.50
</span>20.50 = 20.50
So, there is 164 nickels, and 123 dimes for your answer.

Answer: 2, 9, 14, 17, 19
Step-by-step explanation:
A box plot uses the values: minimum, maximum, median, first quartile and third quartile.
First sort the data from lowest to highest.
2,8,9,11,14,15,17,19,20
Thus, the minimum, or Data Point 1 is 2.
Then find the median.
8,9,11,14,15,17,19
9,11,14,15,17
11,14,15
14
Thus, the median, or Data Point 3 is 14.
For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.
8,9,11
9
Thus, the first quartile, or Data Point 2 is 9.
15,17,19
17.
Thus, the third quartile, or Data Point 4 is 17.
The maximum of the data, or Data Point 5 is 19.
Answer:
x ≥ 168
Step-by-step explanation:
(124 + 188 + x) / 3 ≥ 160 => 312 + x ≥ 480 => x ≥ 480 - 312 ≥ 168
x ≥ 168
God with you!!!
