<em>Answer: 24 </em>
<em>Step-by-step explanation:</em>
Equation: (1/3)x + 4 + 12 = x
Equation: (1/3)x + 16 = x
MULTIPLY EVERYTHING WITH 3
1/3 times 3 = x 16 times 3 = 48 x times 3 = 3x
Equation: x + 48 = 3x MINUS THE "X" BY 3X = 2X
Equation: 2x = 48 OR x = 24
CHECK THE EQUATION:
Sister: 8 Brother: 4 Herself: 12
8 + 4 + 12 = 24

Answer:
Therefore Jenna ran 20 
kilometers in a week.
Step-by-step explanation:
<u><em>Jenna ran 2 7/8 kilometers each day for a week. How far did she run in all?</em></u>
<u><em /></u>
We can simply use proportion to solve this;
But we need to know that 7 days = 1 week
If Jenna ran 2 
kilometers each day, we are now going to find how many kilometers she run in a week(7 days)
Let x be the total distance she ran in a week
2 kilometers = 1 day
x = 7 day
Cross-multiply
x = 2 × 7
= 
× 7
=
=20 kilometers
Therefore Jenna ran 20 kilometers in a week.
