1,3, and 4
Step-by-step explanation:
Answer:
n <=6.5
Step-by-step explanation:
Six less than two times a number is no more than 7
2n-6 <=7
Add 6 to each side
2n-6+6 <=7+6
2n <=13
Divide by 2
2n/2 <=13/2
n <=6.5
Answer:
Candy bar: $1/each
Pop: $2/each
Step-by-step explanation:
4x+3y=10
3x+5y=13
Where x = number of candy bars and y = number of pops.
Create an augmented matrix like so
![\left[\begin{array}{ccc}4&3&10\\3&5&13\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%263%2610%5C%5C3%265%2613%5Cend%7Barray%7D%5Cright%5D)
Using Gaussian Elimination reduce the matrix to reduced row echelon form.
As you can see x = 1, and y = 2.
Thus each candy bar is $1 and each pop is $2.
