Answer:
Step-by-step explanation:
The equations that she wrote are
6x+8y=133
2x=y
The following statements about the system are true
1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
The following statements are wrong because,
2. Because there was no relationship between the number of pipes sold and the size of each pipe.
3. x=2y shows that there are more 8 inches pipes
4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
where is the question , without question how can we find the Values

Step-by-step explanation:
Steps to write equations in augmented form
Step 1
Write the coefficients of the x-terms as the numbers down the first column
Step 2
Write the coefficients of the y-terms as the numbers down the second column
Step 3
Write the coefficients of the z-terms as the numbers down the third column
Step 4
Write the constants which are in the end of equation in fourth column
Yes!
This would be in-fact a linear equation!
<h3>How?</h3>
This equation is set up in y=mx+b form, therefore we know it is a linear equation.
<h3>Example of a linear equation:</h3>
y=12x+2
The 12 is the mx in the equation.
And the 2 is the B in the equation! :)
That is how we solve that.
Any questions?
Have a great day!
