Answer:
A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.

Answer:
$124,400
Step-by-step explanation:
The scholarship pays for 30% of her tuition. This leaves her responsible for 100-30 = 70% of it. 70% = 70/100 = 0.7; this makes her part of the yearly tuition
0.7(29500) = 20650
She is still responsible for her $9600 room and board per year. Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.
Altogether this gives her a total of
20650+9600+850 = 31100 per year. Over the course of 4 years, this will cost her
31100(4) = 124400
Answer: 9/8
Step-by-step explanation:
The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.
The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?
Anyways hope this helped!
27 multiplied by 8 is 216 so she would need a total of 216 cans. If each of the 23 students brings nine cans (multiple 23 by 9) then she has a total of 207. The difference is 9... so she needs 9 more cans
Answer:
2.675
Step-by-step explanation:
The more decimal points there are, the more precise it gets.
2 = 2
2.5 = 2.5
2.675 = 2.675
2 3/4 = 2.75
Since 2.675 has three decimal places, it is the most precise.
