Answer:
This system has one solution (x=2 and y=2), then the answer is A.
Step-by-step explanation:
The system of equations is:
(1)
(2)
Let's multiply the first equation by 2 and subtract it to the second equation


Using this value in (1) we can find y.


Therefore, this system has one solution (x=2 and y=2), the answer is A.

The probability of drawing a two and another 2 is 1/72
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur
- Since the total number in the board game is 9, hence the probability of drawing a 2 will be 1/9
- The probability of drawing the second 2 will be 1/8
- Pr(drawing a 2, then drawing another 2) = 1/9 * 1/8
Pr(drawing a 2, then drawing another 2) = 1/72
Hence the probability of drawing a two and another 2 is 1/72

Define x :
--------------------------------------------------------------
Let the dryer be x.
Dryer = x
Washer = x -53
--------------------------------------------------------------
Construct Equation :
--------------------------------------------------------------
The washer and the dryer cost $847
⇒ x + x - 53 = 847
--------------------------------------------------------------
Solve x :
--------------------------------------------------------------
x + x - 53 = 847
2x - 53 = 847
2x = 847 + 53
2x = 900
x = 450
--------------------------------------------------------------
Find cost of dryer and washer :
--------------------------------------------------------------
Dryer = x = $450
Washer = x = 450 - 53 = 397
--------------------------------------------------------------
Answer: Dryer = $450

4 1/2 divided by 2
First, change 4 1/2 to a decimal
4 1/2 = 4.5
4.5/2
Divide
4.5/2 = 2.25
2.25 is your answer
hope this helps
