There ya go, Hope, this helps
The answer to this problem would be A, $1.15. You get this answer by taking the total cost and dividing that by how many yards of fabric, for example let’s take the first one. $2.53 divided by 2.2 would be $1.15, same goes for the rest.
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.
Question 27 The answer is x = 1 4/11
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.
