Answer:
Step-by-step explanation:
Assuming the system is solvable in the first place, create an augmented matrix of coefficients from the equations. Then put the matrix into reduced row echelon form.
Example is attached.
"Demonstrate by solving the following system."
You need to provide the system of equations.
Answer: I think the answer is #1
Answer:
A. 5:6
Step-by-step explanation:
The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.
Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.
Therefore:
Scale factor = 25:30
Simplify
Scale factor of the smaller figure to the larger = 5:6
Answer:
15 percent
Step-by-step explanation: You will substract the new value from the old value.
23-20
Now you will get the difference between them and divide that by the original amount.
3/20
This will equal 0.15 in which you now multiply by 100
15 percent

The store only sells fabric by the by the quarter yard.
<h2><u><em>
The yellow fabric: 450/36 = 12.5 square yards</em></u></h2><h2><u><em>
The blue fabric: 478/36 is around 13.3 square yards</em></u></h2>
Total Amount: 12.5+13.3=
<h2><u><em>
25.8 square yards</em></u></h2>
