Answer:
23
Step-by-step explanation:
2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
1800
LCM of 10 and 15 = 30
LCM of 6 and 20 = 60
30(60) = 1800
It is just asking you to reorder the number so that the smallest number is first and the largest number is last.
The answer is: 8, 8.261, 8.4, 8.634
