Answer:
11/4 is an improper fraction. 11/4 as a mixed number is 2 3/4 or 2.75, look below for further information.
Step-by-step explanation:
To change 11/4 (an improper fraction) into a mixed number, we need to the denominator (bottom number) by the numerator (top number).
11 / 4 = 2.75
We can then change the 2.75 into 2 and 3/4. Think of a dollar, how many quarters do you need to make a full dollar? Four, and what is the cost of one quarter? 25 cents. 75 divided by 3 is 25. So we can say that 3/4 is equivalent to the decimal 0.75.

Answer:
The laptop was 934 dollars.
Step-by-step explanation:
The equation you should use to solve this is 120 + 11 (74) since the down payment was a one-time thing and she pays 74 dollars for 11 months, not including the first month.
When you solve that, you will get 934 which is the correct answer.
The answer is [-3,2] but the graph isn't on there u cant see. it would be more better understanding if shown the graph to go with it.
Answer:
-5x + 8y = -21
3x - 4y = 15
8y = 5x - 21
y = 5/8x - 21/8
3x - 4y = 15
-4y = -3x + 15
y = 3/4x - 15/4
5/8x - 21/8 = 3/4x - 15/4
-1/8x = -9/8x
x = 9
3x - 4y = 15
3(9) - 4y = 15
27 - 4y = 15
-4y = -12
y = 3
(9, 3)
