45/15=3, so every 3 students must clean 1 mile. 1/3=0.333 forever. Hope this helps!!!
Answer:
<h2>x=0</h2>
Step-by-step explanation:
4x+4=4
-4 to get 4x alone
4x=0
therefore x=0
Answer:
- 3/4 - 1/4 = 1/2
- 5/8 - 1/8 = 1/2
Step-by-step explanation:
You can pick just about any fraction with an odd numerator and find another at distance 1/2 from it.
For example, 5/7 - 1/2 = 10/14 - 7/14 = 3/14. So your subtraction problem can be ...
5/7 - 3/14 = 1/2
Choosing a denominator divisible by 4 can make both parts of the problem use the same denominator.
3/4 - 2/4 = 1/4, so the corresponding subtraction problem is 3/4 - 1/4 = 1/2.
5/8 - 4/8 = 1/8, so the subtraction problem is 5/8 -1/8 = 1/2.
The set is linearly dependent.
To explicitly prove this, we need to show there is at least one choice of constants 
such that
or equivalently,
which is the same as solving the system of equations
From the first and last equations, we have 
and 
. Substituting these into the second equation leaves us with 
, and so the overall solution set is
for which there are infinitely many not-all-zero solutions.
