Answer:
23
Step-by-step explanation:
The median is the number in the middle of the data once it is organized from least to greatest, so that is what we must do first.

There are 19 numbers, that means that the 10th value will be the number in the middle
This means that the median is 23
(1,-4)
x=1, y=-4.
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
5 Boxes
Step-by-step explanation:
Volume is Length * width * height
1 box = 4.5* 2 *4= 36
Each box is 36 cubic feet. Now divide the closet size by box size
185 cubic feet/36 cubic feet per box = 5.138
Since you can't have .138 of a box, and rounding up to 6 boxes is too much, the closet will hold 5 boxes (with .138 cubic feet left over).
Let's try to do this with a little guess and check.
We'll use numbers easily divided by 3 for the older brother's age.
If the older brother is 30, the younger brother is 16. (30 + 16 = 46)
Now, we check that with the 10 + 1/3 the older brother's age.
30 ÷ 3 = 10
10 + 10 = 20
20 > 16
That one doesn't work.
Let's try 24 for the older brother's age.
That means the younger brother would be 22, because 24 + 22 = 46.
24 ÷ 3 = 8
8 + 10 = 18
18 < 22
That one doesn't work, either.
We'll try one more. If the older brother is 27, the younger brother would be 19. (27 + 19 = 46)
27 ÷ 3 = 9
9 + 10 = 19
19 = 19
This one fits all the requirements of the problem.
That means that the answer to the question of "how old is the younger brother?" is
The younger brother is 19 years old.
